>Environment:
Machine: DEC HiNote Ultra II
SCSI-adapter: adaptec AHA-1460
CD-ROM: Pioneer 24x CD-ROM
>Description:
When I access CD-DA via xcdplayer/workman ports, kernel freeze with:
cd0:(aic0:6:0) ILLEGAL REQUEST asc:64,0 Illegal mode for this track
cd0:time out
aic:invalid reselect(idbit=0x40)
aic at line 2241:identify failed
messages. And when I access CD-DA via tosha, kernel shift to ddb
mode with:
aic at line 2393: SCSI-FIFO didn't drain
message.
>How-To-Repeat:
Run xcdplayer, workman, or tosha on my machine:-).
>Fix:
Apply these patches.
