Hmm... none of the debugging messages got triggered, so there should
be no noticeable timing change. It seems like you're being lucky for
the time being. Can you please keep testing and report back?

Hi Tejun,

Just to keep you up informed - this issue is still happening, I've been
testing the latest 2.6.30-git kernels the last couple of weeks and just
checked my logs after having an unexpected fsck upon system boot - the
freeze seems to trigger very infrequently though, since I use s2disk at
least twice a day and the error only seems to have happened twice since
May 2.

I notice that if I hibernate with a CD in the drive and then remove it as soon as I boot, I get a hard reset on the ata1 bus.

I'm not sure if this maybe plays a role in triggering the problem at times, perhaps it is entirely expected - but vim highlights it in red and to a "normal" user that is bad. :)

Maybe after applying your patch I should play around with this?
