The following problem which I reported here on 2nd July seems to be fixed in 2.4.0-test5. I've run bonnie++ all night on a RAID-1 array and it hasn't locked up. Tonight I will test running bonnie++ while a dirty RAID-1 array is syncing and perform a variety of other tests. If I find any problems I'll inform you. Otherwise please assume that this problem is fixed.
