Re: kernel panic

Are you updating from kernel 2.6.18 to 2.6.19?

If yes, read this news.

Re: kernel panic

i think so ,

If you have enabled ide/pata/sata HOOKs in /etc/mkinitcpio.conf the 'ata_piix' module will be used.
This may cause your devices to shift names, eg:
- IDE: devices from hd? to sd?
- SATA: sda might shift to sdc if you have 2 other disks on a PIIX IDE port.
To check if this will affect you, check 'mkinitcpio -M' for piix/ata_piix

yeah it was enabled before i update the kenrel(the partition nam are sda and not hda)

which files i need to edit?
and how i edit them?(i cant do nothing after i get the error(kenrel panic....))

Re: kernel panic

Besides the grub config, you have to edit /etc/fstab. If you have not a live cd where to mount your partition, you can provisionally go back to the old system. In order to do this, change back all the sda to hda in grub and add the kernel boot parameter:

earlymodules=piix

Make these changes when in grub, editing the single lines with 'e'. This will modify the grub config only for the current session. Once inside you system , edit /etc/fstab and recheck the grub configuration.

If after these operations you get kernel panic again, then may be that pata does not work with your chipset and you should permanently go back to the old system (that is go back to hda in fstab and grub config and using the earlymodules=piix boot parameter). Anyway this should happen in rare cases.
