** Tags added: apport-collected
** Description changed:
on this pc, i want to use it as a mediacenter, the system freezes or
hangs randomly.
Observations:
- system freezes definitively, does never wake up from freeze
- when occurring during media playback, audio hangs in a 500ms loop, video
always freezes
- system does not respond to ssh, ping or vnc during freeze
- system does not respond to kernel shortcuts ( e.g. alt+print+reisub )
So the only thing i can do yet is to hard reset the pc, i have not found
a way to get more info for this bug. I just know it happens on mythbuntu
10.04 and 10.10.
I have tried to test the hardware, started with harddisks (both smart and new
partitioning) - nothing
I ran the system for two days without much hardware (only one harddisk, no
pci-dvb-s card, no usb dvb-t) and could not reproduce, so i thought it must be
a hardware problem with one of them. But it happens with either one of them
installed.
