System hangs mostley when the screensaver goes on in
Gnome, it is related to hal, see below. But I have
no clue how to solve it.

This is the what happens in dmesg:

hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command


Output from 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: Inappropriate ioctl for device

And when it happens the system becomes almost unresponsive,
but "top" shows that it is hald-addon-stor that is
consuming all cpu.
