OK, I recently made the mistake of buying a USB case with a drive in it and putting my home directory on it. I have since then had multiple ext3 and ext2 errors: 2.6.8, 2.6.9, 2.6.10 and 2.6.11-rc3 all exhibit the problem within an hour of stress (untarring a fresh kernel tree, cp -al'ing to apply patches repeatedly, my normal workload). I haven't had any similar problems on my internal IDE drive. 2.4 succeeded once, and once had data corruption (although nowhere near as as bad as the 2.6 corruption, and it got much further).
I realize "ub" exists, but it doesn't seem to want to deal with a disk device.
Is USB/SCSI just terminally broken under 2.6? I'll be getting a power supply to test the drive using firewire, which it also supports, to ensure this isn't a disk issue (although the 2.4 goodness undermines this theory).
