Bug Description
I have a Dell Latitude E6420 notebook, with a DVD-RW in it.
When I write DVD-s (to DVD-R discs) the writing speed drops to almost zero and struggles there for about 1-2 minutes. After this the writing completes and the checksum test also pass. This happens 95% of the time when I write movie DVD-s. When I play a disk in a stand alone player which was written with problem indicated here, the playback also struggles at the exact same place where the writing had problems.
If I disable the ACPI SATA mode in bios, the problem disappears. But I need ACPI because of trim command for my SSD.
I tried with divverent disc, same problem
I tried on Ubuntu 11.04 and 11.10, same problem.
