Still some corruption occurs on my root filesystem

[Michael Wahlbrink <x_miw@xxxxxxxxxxxxxxxx>]

Hi,
Got the data back with the xfs_progs from cvs.

All works fine with disabled writecache on the IDE HDDs, untill I saw a 
few reboots later that there was corruption on my root fs again :-(. 
This corruption will not cause the system to hang, but ...... you know....

here's a snippet from my log:
[...]
May 22 10:53:31 monster kernel: FAT: bogus logical sector size 0
May 22 10:53:31 monster kernel: FAT: bogus logical sector size 0
May 22 10:53:31 monster kernel: Invalid ioctl

May 22 10:53:31 monster kernel: XFS: WARNING: recovery required on 
readonly filesystem.
May 22 10:53:31 monster kernel: XFS: write access will be enabled during 
mount.
May 22 10:53:31 monster kernel: Starting XFS recovery on filesystem:

May 22 10:53:31 monster kernel: VFS: Mounted root (xfs filesystem) readonly.
May 22 10:53:31 monster kernel: Freeing unused kernel memory: 204k freed
[...]

The corruption does not disappear, I could only resolve the corruption 
while booting my rescue system and xfs_repair the partition again :-(.

Any Ideas?

And what about the "Invalid ioctl" messages I get aometimes since I use xfs?

don't know what to do now.................................
