Reiserfs has been in the main kernel since 2.4.1-pre4. All you need to
do is enable it when you compile the kernel. The option is
CONFIG_REISERFS_FS under File Systems. You will need to compile it into
the kernel, not as a module to boot your root file system.

Also, make sure you have a recent version of lilo, with reiserfs support.

1. Kernel PANIC: VFS: Unable to mount root fs on 03:43 PLEASE HELP!

Can you please help me with this one?

I have just downloaded the Kernel 2.4.16 (SuSe certified).
It is the first time that I tried to upgrade the kernel (config-compile
etc).
The version I had was the one included in SuSe 7.3 (2.4.10-4GB).
I did some changes to the .config file (via xconfig) but I didn't change
anything on the
filesystems section.

The result is that during xconfig, dep, clean, bzImage, modules, lilo, and
modules_install I HAD NO PROBLEMS what so ever.
When I tried to reboot the machine, it started loading and then stopped
(halted).
The last 5 messages are:

FAT: bogus logical sector size 65422
FAT: bogus logical sector size 65422
UDF-fs: No partitions found (1)
Kernel Panic: VFS: Unable to mount root fs on 03:43
spurious 8259A interrupt: IRQ7

and then stops....

I tried to reconfigure the filesystems section (on xconfig) but I didn't
find anything related to VFS (unless it is there with another name OR if I
am blind! :o )

I am a newbie with Linux and SuSe in particular.

Can you please tell me what is the problem and how can I fix it?
I have NO IDEA what these messages mean (apart from UDF).
....and what is the last message about the IRQ?!?!? It' sounds worrying!

NOTE: When I installed 7.3 in the first place I had NO problems and no error
messages about IRQs etc.
I just wanted to upgrade the kernel in order to install my SoundBlaster
Audigy!

PLEASE help!

Many thanks!
Chris
