[solved]kernel panic after upgrade

hi tonight if upgraded to kernel 2.6.22.1-4 and now i cant boot my system. error message is:

List of all partitions:
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount fs on unknown-block(0,0)

when i add rootfstype=reiser3 to the kernelline, i got this message:

VFS: Cannot open root device "mapper/vg0-lv0" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount fs on unknown-block(0,0)

grub is configured like this:

root (hd0,0)
kernel /vmlinuz26 root=/dev/mapper/vg0-lv0 ro vga=773
initrd /kernel26.img

the same thing happens with the fallback kernel. i hope someone can help me.

Re: [solved]kernel panic after upgrade

It is a failure in script that calls to mkinitcpio: don't find depmod.
It is possible to be solved writing this in the console like root before reinitiating:

mkinitcpio -c /etc/mkinitcpio.d/kernel26-fallback.conf -g /boot/kernel26-fallback.img

and/or

mkinitcpio -g /boot/kernel26-fallback.img

Re: [solved]kernel panic after upgrade

ok,  i don't have an kernel panic anymore, but my system won't start.
when the system starts i'm in the minimal shell, because it cant find my harddisks.

$ echo /dev/*

doesn't list my harddrives

$ lvm lvmdiskscan

lists

/dev/ram0 [    16.00 MB]
.
.
.
/dev/ram15 [    16.00 MB]
0 disks
16 partitions
0 LVM physical volume whole disks
0 LVM physical volumes

i changed nothing in the mkinitcpio.conf the only error message during creating the kernel 26.img is: that it cant find /sys/dev/

i hope anybody has an idea how to solve this

Re: [solved]kernel panic after upgrade

ok, i solved the problem i booted the latest install-cd and started the arch-setup. in the setup i mounted my harddisk and installed the kernel through the setup menu.
