I was having consistent problems with lockups on 2.1.90, 91, and 92.

I've got two machines (virtually identical). Main diff is one is running
RAID5 on three 2G SCSI disks. This machine was running fine on 2.1.89 but
2.1.90 locked up solid within a couple of hours (the other non-RAID box has
had no problems). Rebooting under 2.1.90 again and doing a "ckraid" caused
another lockup within minutes. Same behaviour occurred in 91 and 92 but
disappeared (at least hasn't occurred again) in 93 and 94. Under 90-92 I
could lock up the system every time doing a "ckraid' (I always went back to
2.1.89 for stability).

This seems to jive with the block device problems being mentioned now.
Perhaps the RAID banging on 3 disks is a good way to trigger this? Since
booting on 93 I've not had to do a "ckraid" yet -- might be able to do that
this weekend.

I'm running 2.1.94 now (so far with no problems -- has been up for one day).
