My apologies for the length ahead of time. Per Tejun Heo's request, I
have attached a dmesg with
#define ATA_DEBUG set in include/linux/libata.h
Looks like the dmesg buffer length ran past 16k, but I think the
important parts are in there.
When I get home, I'll try Albert Lee's suggestion for enabling
ATAPI_ENABLE_DMADIR
