Title:
lowlatency-flavour crashes and locks up alot
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
The 3.11 flavour that where upgraded to 3.13 today crashed 10 times
this morning. I have the crashdums, but I figured that it might have
been solved in 3.13. Unfortunatly it seems like it is not.
I will add crashdumps when I get crashes that do not just lockup the
machine but currently I have only seem complete lockups with 3.13
So the essense is :
3.11-lowlatency crashed 10 time today most of the crashes reached the console so I could see the panic text.
3.13-lowlatency crash 1 time 10 minuttes after first boot. No VT swtich. During next reboot it also locked.
