Strange Gentoo v1.4 Issue

AutoBot · l33t Joined: 22 Apr 2002 Posts: 968 Location: Usually Out

Ok I booted the 1.3 iso, wgot the 1.4 stage 3 tarball, installed everything as I have so many times before, I cannot boot for anything. Everytime I try all I get is kernel panic and for the life of me I can't figure the problem, here is a rundown and maybe someone will see something I'm not:

1) My filesystem for root and boot is ReiserFS and I've triple checked the kernel config to make sure ReiserFS is indeed enabled which it is.

2) My fstab is correct as I have triple checked it.

3) Triple checked my partitions and numbers of them, all fine.

4) Mounted my root and boot partitions with the rescue disk and with knoppix without any issues.

5) Properly identified root=/dev/hda3 on my syslinux bootdisk as normal.

So I am at a loss, I have no idea what else to do.....what about any of you?

.: Oh and I have tried mjc-sources and gentoo-sources, current kernel is gentoo-sources.

Yes I get a kernel panic of /dev/hda3 not found, when it's right there and in good working condition.

You used the 'notail' option in grub? (didnt see it mentioned in your list of triple checks)

I use lilo.. can't help you with any other boot manager

Stuff to double/quadrupal check in the kernel... IDE drivers are installed for your chipset? /dev fs support is installed? PC BIOS partition types enabled under Filesystems -> Partition types? (shouldn't need that, but won't hurt if it's enabled) /dev/hda3 not found definitely sounds like more of a kernel config problem than anything.

As you can tell I'm grasping at straws here...

perhaps this helps

disable smp, acip, apic and apm in your kernel...if that helps turn them back on(one at a time) and see if that helps...apic causes kernel panic on all my machines...under lilo there used to be an option to turn apic(or was it acpi ? off..cant remeber.......

IWBCMAN: all those are disabled currently

Pigeon: all systems go there also

.: As you can see by my number of posts that I have been an active gentoo user and have configured a fully working gentoo desktop over 20 times, this issue almost has to be directly related to the 1.4 tarball but I am not positive on this. I appreciate everyones help, looks like I will just have to start from stage 1 and file a bug for stage 3, but what to say in said bug report I have no idea.

Did you try to compile a kernel on another pc and use it to boot on your gentoo 1.4

Because if you get a "kernel panic: unable to mount root fs /dev/hda3"

I can't see the link between this problem and gentoo, because at this moment the only thing that is gentoo specific is the version of the kernel (gentoo-kernel-?) and the kernel's compilation (gentoo's gcc 3.?)

Maybe you should try with a vanilla kernel.

I guess it's not a scsi hdd?!

Why not try ext3 filesytem or heck ext2? Ive seen several post about reisfer probs with the kernels. Its just a thought. Another idea can you make a boot disk from a from a working system with reiser?

I have installed 1.4, all went okay.
I used the stage3 athlon-xp tar ball.
hda2 ext2 boot
hda3 swap
hda6 and hde3 = /dev/md0 reiserfs
kernel = gentoo-sources.

I installed from a working gentoo1.2.

I guess I will start from stage 1 like I usually do.

Oh and it has nothing to do with ReiserFS, I have been using it for along time.

Alright, nobodies posted to this in a few days, but I'm having what seems to be the same problem, and I can't find another thread on it here. The only difference is that I'm using XFS, not ReiserFS, so it seems this problem isn't specific to and particular FS.

Basically, despite the fact that my fstab points to /dev/hda4, a working XFS partition, I still get

XFS: bad magic number
XFS: sb failed...
Kernel panic: VFS: unable to mount root fs on 03:04

upon bootup. Hopefully someone is able to understand what is going on here, as it seems to be gentoo-specific as well.

I guess I was pointing out that maybe he wasn't using 1.4b, and therefor his tips may be misleading. I don't know, I've barely slept in a week.

Actually, my bad it seems. I appear to be behind the times, still running 1.3beta. Sorry guys... although the problem appears to still be exactly the same, and I 'd like to see it resolved in 1.4 before it is released. Well, cheers folks.

have you tried to make an initrd image (mkinitrd) , which will load a reiserfs module when you boot?

Hope this will help you.
