Comment 0 for bug 228624

Scince the hardy upgrade my DVD writer (LG GSA-H55L) is no longer working. Copying files fails with an "Input/output error" and burning a disc stops after a few seconds with nero reporting "DMA-driver error, CRC error". This all worked fine with gutsy and is still working without problems under windows. So it looks like the hardy upgrade broke something.

when trying to copy dmesg reports:
