I know this one :(
It seems to be related to the BIOS spinning up the CDROM and leaving the
IDE controller in some weird state. When we come back the interrupt is
screaming and nobody cares, so it gets disabled. I have no clue yet, how
to handle this.
Disabling the interrupt across suspend/resume helps, but does not work,
when the interrupt is shared with some other device.
