This cdrom drive has defective DMA, leading to kernel panics. I solve this with an /etc/sysconfig/harddiskhda file, and the patch from Bug #63413. The command line for a fix is: hdparm -d0 -u0 -c0 /dev/hda hdparm -i /dev/hda /dev/hda: Model=SONY CD-RW CRX140E, FwRev=1.0n, 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:180,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 mdma2 udma0 udma1 *udma2 AdvancedPM=no
The plan is to disable dma for cdroms by default; due to the shere amount of cdrom drives that get it wrong, combined with the effect ("hang")
Good move.
