Comment 6 for bug 1453543

I used to use the official supported LTS Ubuntu Trusty 3.13 kernel line.
With current updates.
I didn't noticed which subversion started to affect kernel panic after Totem player. May be several months.

I tried to stress several times some kernels by Totem Player (play, seek, switch playlist...):

"4.1.0-040100rc4-generic" OK, never crashed.

"3.16.0-pf4" my own customized with some patches. OK, never crashed.

"3.16.0-37-generic" Utopic actual supported by Trusty. KERNEL PANIC.

"3.13.0-52-generic" Trusty actual. KERNEL PANIC.

"3.16.0-rc3-vanilla" KERNEL PANIC.

A week of testing my own custom build 3.16. Kernel panic never occurred yet.
