>Description:
Western Digital 250GB external drive with Firewire and USB 2.0 interface hangs under high load conditions. Exact symptoms vary either whole machine locks (console dead, no caps lock light) or disk system locks (console responsive as long at no disk access) or just USB drive locks (rare).
Device:
umass0: Western Digital FireWire/USB2.0 Combo, rev 2.00/ff.ff, addr 2
umass0: SCSI over Bulk-Only; quirks = 0x0000
>How-To-Repeat:
Device attached via USB2.0 EHCI driver. Repeated runs of dbench with 20 clients will trigger lockups.
>Fix:
Tentative fix.
