Device Bus Description
------ ---- -----------
3 Std Sony CSD-760S CD-ROM drive
9 Wide 4.3GB Quantum hard drive
aic7870.c version 1.11.2.11 (-stable supped as of May 10th)
>Description:
Hard disk functions normally, but attempting to mount the CD-ROM drive
causes the CD-ROM to be continuously accessed and never mounted.
CTRL-C aborts the mount but the CD-ROM drive activity light continues
and subsequent hard disk accesses are very slow (blocked by the CD-ROM
hogging the bus?). The kernel generates the following messages:
May 11 10:59:47 zen /kernel: cd0(ahc0:3:0): timed out in dataout phase, SCSISIGI == 0x48
May 11 10:59:48 zen /kernel: cd0(ahc0:3:0): BUS DEVICE RESET message queued.

>How-To-Repeat:
Mount the CD-ROM drive :)
>Fix:
Temporary fix: Reverse latest pci/aic7870.c changes back to version
1.11.2.10 Sun Apr 28 19:37:09 1996.
