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 wr...@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 <woll...@freebsd.org> wrote: > In article <4c79499b.3050...@icyb.net.ua> a...@icyb.net.ua writes: >>> [I wrote:] >>> ...say what?
