When I shut down, I get intermittent "hdc lost interrupt" messages.
Here is hdparm for my CDROM:
# /sbin/hdparm -i /dev/hdc
/dev/hdc:
Model=HL-DT-ST DVD+RW GCA-4040N, FwRev=1.17, 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:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 *mdma2
AdvancedPM=no
* signifies the current active mode
# /sbin/hdparm /dev/hdc
/dev/hdc:
HDIO_GET_MULTCOUNT failed: Invalid argument
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument
I still don't like these settings.
I think that unmaskirq should be 1(on). I also think IO_support could
be 32 bit.
BTW: my CDROM won't mount in file manager either. I does mount with
k3b, grip, KsCD.
