Dear Christopher M. Penalver, I am sorry I have upgraded to kernel from Ubuntu Wily (linux-generic-lts-wily 4.2.0.30.24). I have removed Vivid kernel which was very unstable on Supermicro X10DRW/X10DRW-i. The kernel 4.2 runs without troubles so far.
Best regards, Marek Sikl 6.3.2016 v 22:53 Christopher M. Penalver: > Marek Šikl, thank you for taking the time to report this bug and helping to > make Ubuntu better.
