Comment 102 for bug 285392

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:

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.
