After having tested it with the 'solutions' provided in this thread I can say that the bug still affects me.
The DVD burner is correctly identified as UDMA2 both with and without the optios at boot: all_generic_ide=1 irqpoll $ hdparm -i /dev/cdrom /dev/cdrom: Model=TSSTcorp CDDVDW SN-S082H , FwRev=SB01 , SerialNo= Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=unknown, BuffSize=0kB, MaxMultSect=0 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 IORDY=on/off, tPIO={min:383,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 *udma2 AdvancedPM=no Drive conforms to: unknown: * signifies the current active mode Reading DVD/CDs works fine, but I cannot burn.
