Nope, heaps of BUG: at drivers/ata/sata_mv.c:1241 mv_qc_issue() Mainline 2.6.21-rc2 survives moving 4GB around, and reading 30GB or so, but I've not tried anything too stressful yet. I'll leave it up for a bit on that for testing. On 2.6.20-rc6, I started getting errors like sd 1:0:0:0: SCSI error: return code = 0x00040000 end_request: I/O error, dev sdb, sector 6295 sd 0:0:0:0: SCSI error: return code = 0x00040000 end_request: I/O error, dev sda, sector 6439 repeating in the logs (with different sectors), and I couldn't get the drives to come back without a reboot. Unfortunately, I cannot find the logs for the boot and the first set of errors, so this is fairly useless now. I'll just leave 2.6.21-rc2 up overnight and see how it goes.
