Hi everyone,

I've just build my new linux kernel. But it didn't start completely.
When it it tries to mount the root file system, an error occured:

"Kernel panic: VFS : unable to mount root fs on 03:42 "

Does anyone have an idea? I've compiled my new kernel to use the ext2
file system, like my root file system has.

Thank for any help

where 'linux' is your usual boot label, and hdxx is your actual root
device. Once you get it booted, 'man rdev' to figure out how to fix it more
permenantly.

: That's odd... 03:42, as far as I can tell, seems to correspond to a tty,
: not even a block device... anyways, the fix is simple enough.  At the lilo
: prompt, boot with something like
: boot: linux root=/dev/hdxx

I have tried it, but it also didn't work (the same error message occured)...

Did you build a kernel which was compiled for Modules or did you build a
non-monolythic kernel?

The message which you listed has appeared when I changed the scsi adapter
in the machine to one which was not originaly installed. After changing
/etc/conf.modules to install the new adapter it was then necissary to run
/sbin/mkinitrd /boot 2.0.30 . Then run lilo and you should be aok.

You might FIRST just try running lilo to see if that corrects your problem.

I hope this explanation is helpfull. As a newbie to LINUX i may not be
describing enough for you to see what I did to correct the problem.

Please email me and let me know what the solution is/was.
