PostPosted: Fri Mar 04, 2005 5:04 pm    Post subject: [SOLVED] linux-2.6.10-morph25 kernel panic Reply with quote

yup i am trying to build my new reiser4 partitions system with morph-sources, i followed the gentoo handbook for the x86 arch system installation(trying my 2nd gentoo installation). i emerged everything except the X window manager, i try it to emerge kde but got an error i cant remember right now. anyway, i try to boot gentoo with out the lxnay RR4 livecd inside the cdrom. boot manager is lilo, lilo shows red if something is not right, right? my lilo was showing red but i fixed it, now is showing blue, everything i guess is fine for lilo to boot my system except for kernel-2.6.10-morph25, here's what i am receiving for error,

Code:
UDF-fs: No partition found(1)
XFS: bad magic number
XFS: SB validate_failed
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(3,6)


i installed/compiled everything with my second disk being connected as disk number 1 (hda), installation on disk 2 (hdb)
so after finally done the installation i edited /etc/fstab to be /dev/hda* in all partitions, shut down my pc, unplugged disk 1, made disk 2 master and rebooted. i am not sure if this explain why i am getting this error to anyone so i'll add my conf files,

fstab,
Code:
/dev/hda3               /boot           reiserfs        noauto,noatime,notail   1 2

fdisk -l
ntfs partitions are the last partitions but shoing first because i created them before linux partitions.
Code:

/dev/hda11           4386        5222     6723171   83  Linux

Partition table entries are not in disk order


using NPTL with USE flags,
i did,
Code:
nano -w /etc/conf.d/rc
RC_NET_SCRIPT_CHECKING="no"
RC_DEVICES="udev"
RC_DEVICE_TARBALL="no"


there, i dont know what i should do/add more to get help, any ideas how i can fix my problem?

I ran into something like this with the vanilla kernel on my slackware box, and it turned out that I had forgotten to compile in support for my IDE controllers. You might double check that to make sure you have them IN the kernel, NOT as modules.

EDIT: you fixed it before i hit the post button. good job.

are these options availalbe in Device Drivers ---> ATA/ATAPI/MFM/RLL support section?
if so everything in that section are compiled into the kernel

btw i am using genkernel --menuconfig all to compile the kernel

from that little snippet you posted, looks to me that the kernel is trying to mount reiser4 as XFS. You might try another kernel that supports reiser4, such as -cko or -nitro and see if you run into the same problem. I can't tell you much about lilo, as lilo is evil. I use grub exclusively. My Slackware box defaulted to lilo, but i uninstalled it and put grub in there. works much better.

EDIT: also, you might try asking this question in the appropriate morph-sources thread. You might get a little more help :)

please be more specific, i dont know where to get cko nor nitro, they aren't in portage. of course to try them about i need to follow the installation howto kernels respective guides.

Nitro-sources 2.6.11-nitro0 can be found here:

https://forums.gentoo.org/viewtopic-t-302767.html

I can't seem to find an ebuild for -cko, so go here:

http://kem.p.lodz.pl/~peter/cko/

and see what they have to say :)

for nitro, you can either use the install instructions in the first post, or you can follow mine near the bottom of page 6. both methods work.

The appropriate morph-sources (2.6.10-morph25) thread is found here:

https://forums.gentoo.org/viewtopic-t-255721-highlight-cko.html

btw when i chroot to the new environment i want it to see what partitions are mounted and here's what i received.

Code:
lxnaycd / # mount -l
/dev/hdb6 on / type reiser4 (rw,noatime,notail)


should be /dev/hda6 for root partition and because there's no other disk connected.

that part looks right, but you gotta remember, lxnay's livecd uses the nitro-sources kernel (or at least, he used to) :). judging on what that little dmesg snippet that you pasted said, 2.6.10-morph25 is trying to mount reiser4 as XFS. that's not correct, if i remember right.

edit, didn't see the /hdb and /hda. if the drive you unhooked is the master, then yes, it's going to show it as hdb. if you unhooked the slave, then hda would be right.

/dev/hda, /dev/hdb, /dev/hd<whatever> doesn't matter. it's determined by the order in which the bios detects the drives. Here's how it does it:

Primary Master: /dev/hda
Primary Slave: /dev/hdb
Secondary Master: /dev/hdc
Secondary Slave: /dev/hdd

and you'd keep going if you had another add on card.

my slackware box detects the drive that the system boots from as the primary slave, hence having a /dev/hdb but no hda. the 120G HD in that machine is hooked to an add-in card, and it's the primary master on the add in card, so that 120G is /dev/hde. I don't know if i'm confusing you any more or not, but look at your dmesg snippet in the first post. it can't mount root because it's trying to mount /dev/hda6 (which is reiser4) using the xfs mounter. That doesn't work.

try an fdisk -l /dev/hda and see if partitions show up. if they don't, then change your bootloader config to point to /dev/hdb and change your fstab to match.

i am compiling nitro-sources rigth now, i really hope this will solve the problem... if not i will change my root partition in /etc/fstab to be /dev/hdb6, but, i guess i will have to change all the other partitions aswell. if my second choise works, i'll leave nitro-sources as my kernel and later download lxnay-sources.

i hope it work this time, i am getting tired to mount ALL my partitions lol

Hi,

it looks like you should set your hard disk's jumper as "master". Otherwise it will stay as /dev/hdb. The "name" of an hard disk is determined by how you set it up (i.e., on primary or secondary IDE, and as "master" or "slave").

thanks, solved that problem by installing the lxnay-sources, my hard drive was set for cable select master. in the boot process the bios is showing my disk as primary.

anyway i'm installing the new morph-sources right :D, meaning finishing the installation,..installaging xorg..fvwm...all the rest. thanks for this kernel dude! i hope it will work for me.
