Kernel 2.2.0 destroyed filesystem
I tried to upgrade my kernel from version 2.0.34 to 2.2.0, but this
resulted in destruction of all linux partitions. This has happened
previously on this same machine as I tested development kernels (2.1.126,
2.1.128 and 2.2.0-pre8) using Red Hat 5.0 and Debian hamm. This time I
first upgraded all the software recommended in Documentation/Changes,
although it didn't make any difference in the end.
I've never run into this problem using series 2.0-kernels.
Bootup stopped in kernel panic:
---
Partition check:
hda:hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
hda: set_mutlmode: error=0x04 { DriveStatusError }
hda1 hda2 < hda5 hda6 hda7 hda8 >
EXT2-fs error (device 03:06): ext2_check_descriptors: Inode bitmap for
group 1 not in group (block 0!)
EXT2-fs: group descriptors corrupted !
There were changes in ide-disk.c that would enable mult_mode
(under conditions differing from what we had earlier).
There is (or was in recent 2.2.0preX kernels, I have no
kernel source nearby right now) an #if 0 (or #if 1) that you
can change to #if 1 (or #if 0), and see if that helps.
[Search for multmode, the context will be clear.]
For at least one person that solved his problems.
