BTW, it seems that DVD burning with ahci is broken, burning a CD is okay, but I never burn a DVD sucessfully with ahci. Always get somethings like "unable to write@60H input/output error" and many "(cd0:ahcich2:0:0:0): SCSI sense: ILLEGAL REQUEST csi:43,0,0,c asc:24,0 (Invalid field in CDB): Command byte 6 is invalid" in dmesg, With ahci unloaded, I see "(cd0:ata4:0:0:0): SCSI sense: ILLEGAL REQUEST csi:43,0,0,c asc:24,0 (Invalid field in CDB): Command byte 6 is invalid" once, but it works. But I can read data DVD with ahci and sucessfully verify data with diff. --Buganini On Sat, Aug 28, 2010 at 5:41 PM, Garrett Wollman <wollman@freebsd.org> wrot= e: > In article <4C79499B.3050305@icyb.net.ua> avg@icyb.net.ua writes: >>> [I wrote:] >>> ...say what? =C2=A0Why is the cd driver suddenly returning ENXIO? >> >>Strange indeed. >>Can you dtrace this read? =C2=A0You can use combination of syscall and fb= t providers >>with execname predicate. > > You're going to have to be much much more specific than that. > > -GAWollman > > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org= " >
