SCSI burning

HI all. after upgrading from 8.1 to 9.0 I'v problems with CD burnig . On all kernels athlon and two SCSI controlers I'v that messages: Jan 15 22:57:45 linux kernel: scsi : aborting command due to timeout : pid 7686, scsi0, channel 0, id 0, lun 0 Test Unit Ready 00 00 00 00 00 Jan 15 22:57:45 linux kernel: DC395x_abort: pid=7686, target=00-0 Jan 15 22:57:45 linux kernel: pid 7686(1097217):00 00..(0-0) abort (SU)!* Jan 15 22:57:45 linux kernel: TmpSRB: Jan 15 22:57:45 linux kernel: DC395x: Aborted pid 7686 with status 1 Jan 15 22:57:55 linux kernel: scsi : aborting command due to timeout : pid 7687, scsi0, channel 0, id 0, lun 0 Test Unit Ready 00 00 00 00 00 Jan 15 22:57:55 linux kernel: DC395x_abort: pid=7687, target=00-0 Jan 15 22:57:55 linux kernel: pid 7686(1097217):00 00..(0-0) abort (SU)!pid 7687(1107217):00 00..(0-0) abort (SU)!* Jan 15 22:57:55 linux kernel: TmpSRB: Jan 15 22:57:55 linux kernel: DC395x: Aborted pid 7687 with status 1 Jan 15 22:57:55 linux kernel: SCSI error: host 0 id 0 lun 0 return code = 26030000 Jan 15 22:57:55 linux kernel: Sense class 0, sense error 0, extended sense 0 Jan 15 22:58:05 linux kernel: scsi : aborting command due to timeout : pid 7688, scsi0, channel 0, id 0, lun 0 Test Unit Ready 00 00 00 00 00 Jan 15 22:58:05 linux kernel: DC395x_abort: pid=7688, target=00-0 Jan 15 22:58:05 linux kernel: pid 7686(1097217):00 00..(0-0) abort (SU)!pid 7687(1107217):00 00..(0-0) abort (SU)!pid 7688(1117218):00 00..(0-0) abort (SU)!* Jan 15 22:58:05 linux kernel: TmpSRB: Jan 15 22:58:05 linux kernel: DC395x: Aborted pid 7688 with status 1 Jan 15 22:58:15 linux kernel: scsi : aborting command due to timeout : pid 7689, scsi0, channel 0, id 0, lun 0 Test Unit Ready 00 00 00 00 00 Jan 15 22:58:15 linux kernel: DC395x_abort: pid=7689, target=00-0 Jan 15 22:58:15 linux kernel: pid 7686(1097217):00 00..(0-0) abort (SU)!pid 7687(1107217):00 00..(0-0) abort (SU)!pid 7688(1117218):00 00..(0-0) abort (SU)!pid 7689(1127218):00 00..(0-0) abort (SU)!* Jan 15 22:58:15 linux kernel: TmpSRB: Jan 15 22:58:15 linux kernel: DC395x: Aborted pid 7689 with status 1 Jan 15 22:58:15 linux kernel: SCSI error: host 0 id 0 lun 0 return code = 26030000 Jan 15 22:58:15 linux kernel: Sense class 0, sense error 0, extended sense 0 Or: Jan 14 23:54:28 linux kernel: DC395x: Aborted pid 905 with status 1 Jan 14 23:54:37 linux kernel: DC395x: sg_to_virt failed!
