Kernel Panic

No Filesystem could mount root, tried:
Kernel panic - not syncing VFS: unable to mount root fs on unknown block (0,0)

cannot boot up on kernel 2.6.19-3

menu.lst changed the root= from hd to sd on kernel line also added the append piix thing

fstab is   hd   to sd

Re: Kernel Panic

Are you absolutely sure that you have any use for the pata hook?

Re: Kernel Panic

Same.. or well, similar thing here:

upgraded to 2.6.19 today and:

ERROR: failed to parse block device name '/dev/hda3' unknown"
ERROR: root fs cannot be detected. Try using the rootfs=kernel parameter
...
...
Kernel paniox - not syncing: Attempted to kill init

I'm a complete kernel noob. Tried to change hda to sda in grub's menu file and to replace ide with pata in mkinitcpio.conf.. nothing changed. Always the same error.

Re: Kernel Panic

Guys, there is a message above the panic, with a workaround. Just read it and do it.

Re: Kernel Panic

That is not what I meant. You can do it without changing fstab by getting the old driver back. All you need to do is add "earlymodules=piix" to kernel commandline and old hdXY naming will be back. BTW, in the boot process, before the panic, it tells you to do exactly that, but if you refuse to read, then you can't be helped.

Re: Kernel Panic

I have ide drives, changed my fstab and bootloader, everything works fine.

unfortunately HAL no longer automounts dvds. Anyone know why this might be? I was also expecting to see sdc (my dvd drive was hdc) under /dev but it isn't there. dvd and cdrom have gone too

can anyone let me know why??

cheers

Re: Kernel Panic

Optical drives are named as /dev/srX, so your dvd probably gets a /dev/sr0 if this is your first one. So you have to correct your fstab for accessing the device.

Re: Kernel Panic

what could have gone wrong?
