Well, it was a chance :) However, I had io_32bit=1 but I also had a freeze even after setting it back to 0.

I found a few things: 1st: it happens when the disk is loaded: best way to freeze the system here is a find over a big subtree (something around 60.000 files in lots of directories, ext2), better some of them in parallel and even better some find -print0 | xargs -0 cat > /dev/null. But even there: it doesnt happen all time, the chances just grow up. 2nd: it seems, the disk spins down short before the error appears. At least all time when I was in front of the machine when the problem appeared, I heard the disk spinning down - just as if it was gone to standby mode. But it was definitely loaded before (I hear the head seeks and then the spindown). And no, I dont have any automated spindown like noflushd or something like that.
CC:ing to lkm again. Probably this helps somehow.
