On Monday, Feb 18, I posted a message that 2.4.18-pre9-ac4
fails to boot on my machine with
FAT: bogus logical sector size 0
FAT: bogus logical sector size 0
Kernel panic: VFS: Unable to mount root fs on 03:00
messages. 2.4.18-rc1, and many different kernels, do not have
troubles of that sort. Tonight I found to my dismay that the
same trouble afflicted 2.4.18-rc4. No, I do not know why this
happens; at least at this moment.

Good day, Michal,
(My apologies in advance if your problem is not a mischosen root
partition).

See http://www.uwsg.iu.edu/hypermail/linux/kernel/0111.3/0454.html
; the post refers to the fact that the kernel doesn't know what filesystem
is being used on the root device, so it tries all of the filesystem
drivers. The fat filesystem is whining because it can't recognize a fat
filesystem on /dev/hda...
> Kernel panic: VFS: Unable to mount root fs on 03:00
The 03:00 seems to imply to me that the kernel is looking for a
root filesystem on /dev/hda (see /usr/src/linux/Documentation/devices.txt
). Is your root filesystem truly on /dev/hda (the entire drive), or (more
likely) on one of the partitions, such as /dev/hda1, /dev/hda2, etc.?
If your root filesystem is on one of these others, you can tell
the kernel what partition to use with:
rdev /path/to/my/kernel/file /dev/hda9 #Replace hda9 with your root partition
or autodetect the partition with:
rdev /path/to/my/kernel/file `cat /etc/mtab | grep ' / ' | cut -f 1 -d ' '`
If you're booting this kernel from a floppy, make sure
you tell that kernel to use the right root as well; redo either of the
above with
rdev /dev/fd0 /dev/hda9 #Replace hda9 with your root partition
rdev /dev/fd0 `cat /etc/mtab | grep ' / ' | cut -f 1 -d ' '`
You might also want to check your boot loader's configuration file
and make sure that it references the correct root filesystem.
/etc/lilo.conf:
image=/boot/bzImage-2.4.18-3
label=2.4.18-3
root=/dev/hda4
read-only
Cheers,
- Bill

Well, I still do not know the answer; when I started to investigate it
decided to work and I am running it right now. Bootloader not in a
mood? Quite possible. Boot commands used with 2.4.18-rc1 and
2.4.18-rc4 differ by one character (more precisely, a digit :-). Sorry
for a premature alarm.
BTW - I noticed that although I wrote that Monday I failed to mention
this in the message quoted. The machine is Alpha (Nautilus).
