I suspect this is the same problem I've encountered with a Toshiba DVD/CDRW
drive on a ServerWorks CSB5 controller. The following change re-enables some
code to workaround a missed interrupt and allows my system to boot::
diff ./ata-queue.c /data/devel/netperf/dev/ata/ata-queue.c
319c319
< #if 0
---
> #if 1
However the Toshiba drive is not recognized. If after booting I do:
atacontrol reinit 1
I sometimes get the drive properly probed. sos sent me the following change
to try but I still haven't gotten to it. Beware that it's probably out of
date wrt current source:
