Re: new kernel panics

Just compiled my 1st kernel.

Using sources from 2.6.18-4 (((((((((same as present kernel to keep it
simple)

Compiled ext3 & ext2 into the kernel (not as modules)

installed kernel & modules

installed into grub

root (hd0,0)
kernel /vmlinux root=dev/hda2 ro noinitrd
save default

The stock kernel was

root (hd0,0)
kernel /vmlinux-2.6.18-4-686 root=/dev/hda2 ro
initrd /initrd.img-2.6.18-4-686
savedefaults

The stock kernel works, the new kernel fails after 20 lines (or so)
with:-

please append correct "root=" boot optopns

kernel panic - not syncing: VFS: unable to mount root fs on
unknown-block(0,0)


I have tried all combinations of (hd0,0) & 0,1 & root=/dev/hda1
& 2. There is no initrd for the new kernel which is what I want
file systems hda1 is /boot & hda2 is / & both are ext3

I have been presuming it to be a grub menu.lst problem but it could be
a kernel compile problem. I would have thought that if so it would
have to be around the ext3 file system but it seems to load something
before it panics so I would think that is OK

Can anybody suggest anything else - PLEASE

Steve



Have you compiled the driver for your motherboard IDE/SATA controller into the kernel. If its a module and no initrd then grub will not be able to see the disks, let alone the partitions :)
