cdrecord, Kernel 2.6: possible drive buffer underruns predicted

Hallo *,

ich habe Sid mit Kernel 2.6 und cdrecord 2.01a19. Als GUI für's
Brennen nutze ich nebenbei xcdroast;)

Nach jedem Brennen wirft mit cdrecord aus:

Total of 1 possible drive buffer underruns predicted.

Da war aber keiner. Mit Kernel 2.4 und der SCSI-Emulation gab es
keine Fehlermeldung. Hier das log:
