Public bug reported:
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:
