It seems this bug affects SATA CD/DVD burning as well, that means it is very likely that you burn saucers instead of usable disks. At the middle of disk writing the following entries appears in system log: Sep 29 21:28:12 mackor-desktop kernel: [ 5548.919716] ata3: SError: { HostInt Handshk } Sep 29 21:28:12 mackor-desktop kernel: [ 5548.919729] ata3.00: cmd a0/01:00:00:00:f8/00:00:00:00:00/a0 tag 0 dma 63488 out Sep 29 21:28:12 mackor-desktop kernel: [ 5548.919732] cdb 2a 00 00 00 01 b2 00 00 1f 00 00 00 00 00 00 00 Sep 29 21:28:12 mackor-desktop kernel: [ 5548.919734] res 50/00:03:00:00:f8/00:00:00:00:00/a0 Emask 0x50 (ATA bus error) Sep 29 21:28:12 mackor-desktop kernel: [ 5548.919739] ata3.00: status: { DRDY } Sep 29 21:28:12 mackor-desktop kernel: [ 5548.919750] ata3: hard resetting link Sep 29 21:28:12 mackor-desktop kernel: [ 5549.404553] ata3: softreset failed (device not ready) Sep 29 21:28:12 mackor-desktop kernel: [ 5549.404564] ata3: failed due to HW bug, retry pmp=0
As I saw red hat has a patched kernel with which you can turn the PMP feature off with pmp=0. The error message improvement has been integrated into Ubuntu so we are notified now, but unfortunately telling pmp=0 to the kernel does nothing at all. -- Softreset failed (device not ready) https://bugs.launchpad.net/bugs/285392 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
