[Bug 54366] Hard lock while ripping audio cds

[Ernst Persson]

Public bug reported:

Binary package hint: linux-source-2.6.15

I'm plauged by some kind of kernel panic when ripping audio cds in
Dapper.

The ripping is done with rhythmbox.
The system log reports io timeouts a few times before the hang, however I haven't seen any errormessage from the hang/panic itself.
The computer becomes completely unresponsive.
The cdrom says this:   (hdparm.conf has not been modified)

sudo hdparm /dev/hda

/dev/hda:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Invalid argument

sudo hdparm -I /dev/hda

/dev/hda:
