>Description:
My new PC at work gives me this dmesg. It says (see below):

wdc_atapi_intr_drq: Unexpectedly in the command phase. Please report
this.

The kernel config is a copy of GENERIC with just option
FFS_SOFTUPDATES added. It is built from current sources as of
ctm-delta 1095. A 2.6 kernel gives the same dmesg. 2.5 runs fine. The
mainboard is by GigaByte with intel BX440 chipset. The undetected
atapi CDROM drive is a LiteOn 40x.

>How-To-Repeat:
Boot this machine with a 2.6 kernel. ;-)

        
>Fix:
Running 2.5 is a workaround. The CDROM works fine with 2.5. I don't
know whether this is is related to the board, the chipset, or the
CDROM drive. I could supply a 2.5 dmesg output, if that helps.
