kernel panic

Hi, I just encounted a problem with my linux box(kernel version 1.2.3) when I
booted it up. It seems that my kernel was booted up all right, but when it tried
to mount the root, the problem occurs. The following messages appeared on
the console:

[booting kernel ok]...
...
VFS: Mount root (ext2 FileSystem) readonly
hda: read_intr: status=0x59 {DriveReady SeekComplete DataRequestError}
hda: read_intr: error=0x01 {Addr Mark Not Found}
/lib/lib.so: Cache '/etc/lib.so.cache' is corrupt
end_request: I/O error, dev 0302 sector 425998
Kernal panic: EXT2-fs panic(device 3/2); ext2_read_inode: unable to read i-node block_inode=52433, block=2129999

I don't know whether it's my hard drive problem or just one file
'/etc/lib.so.cache' is corrupt. I can't do anything after it hanged there.
My hard disk is devided into 3 partitions:
        hda1: DOS
        hda2: LINUX
        had3: swap space
DOS and Windows work fine, I just can't mount linux filesystem anymore(I've been
using it for more than a year without problems) . Is there a way of saving my
linux partition without re-installing it?

Any help will be greatly appreciated. Thanks.

I would try booting from a boo/root floppy set, then run e2fsck on your
(unmounted) linux partition.

1. panic not rebooting even though /proc/sys/kernel/panic=1?

Anyone know why a kernel panic would not cause a reboot even though /proc/sys/kernel/panic is set to "1"?

This morning I had the following message on the console of a 2.2.14 box that had been sitting idle overnight:


When I pressed ENTER, I found that bash was still responding, though when I tried to run "top" everything froze until I pulled the plug on the box:


   total 3
   drwxr-x---    2 root     root         1024 Nov  7 23:56 .
   drwxr-xr-x   13 root     root         1024 Nov  7 19:56 ..
   -rw-------    1 root     root            5 Nov  7 23:56 test.txt


   Kernel panic: Free list corrupted

1) Anyone know why the kernel panic didn't cause a reboot?

2) Or maybe why something like this would even happen?

Thanks,

Stphane Charette
