Hi,
we can now reproduce the problem, but it looks like the problems are not caused by the kblockd.
The problem on this host is that from time to time "ps -aux" just hangs and starts eating up all memory. When it has taken enough, either some kblockd message occurs, and/or the oom killer jumps in and starts killing threads. So, the ps -aux hangs *before* the kblockd messages occur, and is not caused by it (like I assumed before). And since I don't get any disk errors etc. after the kblockd messages, I guess everything is fine and the scsi operation indeed recovers the way you said it should.
Now we just need to find out why ps -aux hangs. Seems to be a problem with the nfsd, because it hangs when showing the [nfsd] entries and works after restarting the nfs server. In case someone is interested in this issue, I described it in more detail on the nfs list at http://marc.theaimsgroup.com/?l=linux-nfs&m=110509676609987&w=2
Thanks for your help! cu, Frank
