[[Patch omitted.]]
I've been using the patch Ian posted for a week or so now and have not
had any of the serious problems I had before I applied the patch. I
have had two incidences of "TIMEOUT - WRITE_DMA" in the time I've been
running with the patch, but they have not resulted in the "FAILURE -
WRITE_DMA timed out" and associated fatal provider disconnection I
experienced previously. It may be completely unrelated, but since
running with this patch, my system also hasn't experienced any of the
occasional spontaneous reboots I would sometimes get before, and seems
overall more robust.
It would be great if this patch could be applied to -CURRENT and MFC5'd,
too.
Cheers,
Paul.
