I'm having errors in my CD booting (and it's not corrupted)

[alegermer]

I'm having a major problem here... I'm trying to install Gentoo in my AMD64 architecture machine and in all my attempts I'm getting error before starting to do anything. I've alrready tryed with universal and minimal CDs, both are having the same problem (and I've already burnt 3 CDs with this joke). As soon as I boot, the kernel starts loading them it's prompted the keyboard-type menu, till here everything ok. them... after mounting the CD room and other configurations, exactly after the line

Code: Select all

booting(initramfs)

I get a hurricane of errors, the screen starts to scroll quickly and, in most times, I get the error

Code: Select all

SQUASHFS error: ZLIB_FS returned unexpected result 0xfffffffd
SQUASHFS error: unable to read page, block 12bcc34, size 6054

it's relevant to say that these messages are not always the same, but basically, they are related to zlib_fs. I looked for people with the same problem I'm havings, but I didn't find anyone... Please, I don't know what to do

details about my hardware:
AMD 64 K8 300+ 754 processor
K8V-X Motherboard
512 RAM
HD MAXTOR 60gb
DVD RW LG
Radeon 9600

Anyone can help me?

PS: strangely after some tryes, my PS2 mouse is disabled and I need to reset the font to have it back working

if you need that cd for installing gentoo you coul'd try a KNOPPIX live-cd or similar - works the same way as the gentoo-one.
maybe you can give it a try and change your cd-rom-drive? hat this errors on SCSI-CDrom-drives !

I think I am having the exact same problem. Here's what i've managed to get of the error messages

Code: Select all

>>Determining root device...
>>Determining looptype...
>>Mounting squashfs filesystem
>>Copying read-only image to tempfs
>>No cdupdate.sh found, skipping
>>Booting (initramfs)

It then loops the following error message

Code: Select all

Buffer I/O error on device hda, logical block xxx
hda: media error (bad sector): status = 0x51 {DriveReady SeekComplete Error}
hda: media error (bad sector): error = 0x30 {LastFailedSense = 0x03}
ide: failed opcode was: unknown
end_request: I/O Error, dev hda, sector xxx

The numbers (xxx) vary and normally increment variably, but occasionaly they go down as well. The logical block number is normally around 120 and the sector number is normally around 512.
At about every 10 iterations of the above error message it gives:

Code: Select all

SQUASHFS error: ZLIB_FS returned unexpected result 0xfffffffd
SQUASHFS error: unable to read page, block 12bcc34, size 6054

All I could deduce from the error was that it was trying to access the IDE hard disk, remaining blind to the fact that there wasn't one. Perhaps someone else, more enlightened than me could help me out?

TIA

BTW My Hardware is:
AMD64 XP 3000+
Asus K8N Motherboard (n-force 250)
512MB Geil RAM
Maxtor 80GB SATA HDD
Hurcules ATi Radeon 9800 Pro

[EDIT]I also checked the md5 sum of the file, and the ISO is NOT corrupt[/EDIT}

It is possible to make install passing the parameter "ide=nodma" to kernel. mI didn't really understand why this is happening, but I realized that maxtor's hds are having many problems with linux kernel dma (does't mind if it's sata, ata or pata). Indeed, everything rus ok after that, you do not even need to pass the same instruction to the compilled kernel. I think it's just a conflict between linux kernel dma and maxtor hds. I haven't seen really a performance loss and I'm wondering if we couldn't be ok without maxtor's dma support. everything running ok for my view! =)

I tried ide=nodma, ide=reverse and noapic options. Neither worked. I think its a bug on the 2005.1 livecd. I just used bored and 2004.3 instead. I *think* this is a bug. I'll probably see if it needs to be reported or whether it already has.

if you need that cd for installing gentoo you coul'd try a KNOPPIX live-cd or similar - works the same way as the gentoo-one.

Wasn't sure if that'd work. AFAIK knoppix is 32 bit and i wanted a native 64bit install.

I have Vaio vgn-a215m.
Yestarday I updated the dvd-+rw firmaware, but now I can't install gentoo. I have the same error...


edit:

@alegermer: ok, I try to install with 2004.3 and always works.
In my opinion (maybe) the 2005.* doesn't had a "multimode support" in kernel...

I'm also having problems with the 2005.1 CD; however, my problem is that I get messages along the lines of:

Activating udev
making tmpfs for /newroot
attempting to mount cd:- /dev/cdroms/cdrom0
attempting to mount cd:- /dev/hda
attempting to mount cd:- /dev/hdc
No bootable media found
could not find CD to boot, something else needed!

The wonderful irony in all this is that the system is purely vanilla parallel-ATA, and the livecd's work for every version I've tried EXCEPT 2005.1. Disabling/enabling options almost made no difference -- there was one exception: ide=nodma seems to have helped a little, and is good enough for my purposes. Sorta.

The knoppix CD doesn't work the same way as the Gentoo CD; I've dug into customizing both. More importantly, (for my needs, at least) the knoppix CD is actually more broken than the Gentoo CD, and is far more buggy and in general unreliable. I may end up just changing the kernel that the LiveCD uses, and re-mastering it from there...

Hi,

I have the same problem.
Look at this picture

Any solution found ?

Hyp: I've been able to replicate your problem (exactly), however the solution isn't what I'd call wonderful.

Since I've been digging into the LiveCD's themselves, and re-forming it to suit a different set of demands, I've been able to learn quite a bit.

The bottom line is that the LiveCD's kernel configuration is what I would call 'messed up'. The entire point of the Gentoo LiveCD is to allow a user to install the OS; so it makes sense to attempt to avoid 'features' that while interesting for use on a desktop, don't necessarily make sense when you're installing the OS for the first time. In this case, the LiveCD's kernel was compiled with options that can (and does) break on certain hardware sets.

So, I actually modified a LiveCD 2005.1 CD, but used a different kernel than comes with the official LiveCD, using more sane options. (This was the only necessary difference).

Obviously, this isn't a great 'general' solution. I'm dissapointed that the Gentoo people were so careless with their kernel config on this LiveCD.

A decent solution that will work is to use the LiveCD 2005.0 (minimal) to boot. Then use the 2005.1 base image and/or stage tarballs, sync up portage and start building. The minimal CD is actually quite version-neutral; you just need it to partition/format the hard disk drives, and unpack the current 'base' gentoo image. Then you chroot into that -- once you've chrooted, it doesn't matter that you booted from a different LiveCD than Gentoo's -- the 2005.0 part isn't visible within the chroot. Which means you won't get a 'polluted' install in any way, shape, or form.

For an example of how neutral the Gentoo LiveCD can be: You can actually install SuSE with a Gentoo LiveCD; it takes a bit of work, and a complete lack of sanity, but it can be done. (Why you'd want to is another matter...)

I think you fail to appreciate the fact that the developers are doing this for free, there are a limited number of developers with limited time. And the amount of different hardware out there is just plain enormous. It is simly not feasible to test every single combination of hardware components out there.

But please do file bugs when you find problems so they can be fixed in the next livecd. And if you can find time to test betas and release candidates of the livecds that would be great, since you can help make them better that way.

My config:

nVidia nForce3 250Gb mobo
2GB patriot memory (400Mhz, 2x1GB)
Maxtor 6L200S0 (according to dmesg)
AMD Athlon 64 3400+

ide=nodma fixed the SQUASHFS error for me.

[wickedwicky]

Mainboard: Gigabyte K7 Triton 400 series (7VAXP Ultra)
Memory: 3x 1GB
Harddisk: Several, hda is a WD 200GB
CD-ROM: A-OPEN DVD+/- rewriter 8x

ide=nodma fixed my problem with the latest minimal-install iso.

I guess when using DMA it tries to use uDMA133, (equal to hdparm -X68) while the IDE1 controller on this mainboard when configured in "CD-ROM" mode only supports uDMA66 (equal to hdparm -X66)
