timeouts on ATAPI cd-burner

Hello,

I have upgraded to 5.2-CURRENT #5 from yesterday, to
test if the following commit fixes my problem,
beeing to able to write to an PHILIPS CDRW48P P1.6
ATAPI burner using cdrecord:

Revision 1.33 / Wed Feb 11 10:14:08 2004 UTC by thomas

(atapi_cb): Reenable automatic retrieve of sense data on error, making
it asynchronous to avoid incorrect use of ata_atapicmd within an
ATAPI callback.

Cdrecord still hangs and throws a timeout after some minutes,
leaving the burner unsuable until a system reboot.

Trying to abort the record command before the "9 second timeout"
gives (sorry for long lines):
