Re: Oops on boot with TCQ enabled (VIA KT133A)

Still when enabling tcq via 'echo using_tcq:8 > /proc/ide/hda/settings' doing
a simple 'bk clone' of the 2.5 repository will frag the newly created files
uttlery. Lots of unconnected inodes and illegal directory entries on reboot.
Filesystem is ext2. Enabling tcq and doing light work, watching movies, using
mozilla, ... seems to work fine - but my home directory is on nfs, so it's no
real test for my system disk.
When disabling tcq after boot, nothing of this happens.
Increasing the queue size to 32 seems to speed things up (no reliable numbers
here). Complete system info at http://lx.sfhq.hn.org/.
Can I somehow debug tcq?
