[Bug 879183] Re: mythbackend causes kernel panic and reboots

 

apport information

** Tags added: apport-collected oneiric running-unity

** Description changed:

  I am getting a "Kernel panic - not syncing: Fatal Machine check" from
  both mythtv-backend, mythcommflag, and I think mythtv-frontend.
  
- My pc was running fine on 11.04, and I started getting these immediately
- after the upgrade to 11.10.  I thought there was an outside chance it
- was being caused by bad power or overheating cpus, so I did a stress
- test but that did not cause a kernel panic.  So I decided to reinstall
- ubuntu, this time I used 11.10 32-bit.
