I tried to follow the git-bisect manpage (and have successfully used
bisect in the past a few times), but I think ~5700 revisions between
2.6.24 and 2.6.25 are just too much fuzz. The bisect logs so far, with
my comments inbetween:

Christian, what is the test you are using for the bisect?

Sorry, I don't understand: which "test" do you mean?

I did the bisect as per the bisect log and then just rebooted. Which gave me no usable results yet. I'm trying to boot 2.6.25-rc1 in a few moments and see if the hang is there as well. If it is, I'll start bisecting again and hope that "halfway between -rc1 and .24" will be a bootable kernel this time...

The "error" I'm trying to chase is a system "hang", but no instant lockup. I can reproduce this by increasing disk I/O. I did this primarily with rsync from different filesystems to my backup XFS partition. After a few minutes, the INFO: messages[0] appeared.

Thanks,
Christian.
