Alright. I took my x86-64 machine and installed FC2-test2 on it and it
has the problem (original). I then just took the DVD and burnt me
a new one. Same problem, naturally. Then I changed booty and added
some code that checked if /proc/sys/fs/xfs/sync_interval existed and
was writable at all and if it was, it wrote 1000 to it (1 second).
Then I added a time.sleep(5) (5 seconds delay), a few more isys.sync()
after that and finally another time.sleep(5) just to be on the safe
side. And guess what - still no go :(

At least I now have something I can work with again.

Any more ideas?

The kernel is based on 2.6.3 and I haven't looked into it if they patch
anything relevant for us.

Any more things anyone wants me to try - go right ahead and ask - it now
takes me only roughly an hour to build and burn and test it, so
it's not really painful as most of it's automated.
