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.
This is the message I get any time I enter a blank dvd (tested with DVD-R)
[ 177.784082] cdrom: This disc doesn't have any tracks I recognize!
[ 178.306282] end_request: I/O error, dev sr0, sector 0
[ 178.306294] Buffer I/O error on device sr0, logical block 0
[ 178.504803] end_request: I/O error, dev sr0, sector 0
[ 178.504817] Buffer I/O error on device sr0, logical block 0
As reported in the thread (#76), I sometimes manage to burn small size files
(although I try various speeds the burner never works faster than ~1.5X)
Trying to burn a DVD of about 3GB (or more) data inevitably fails.
