Title:
System hangs randomly
Status in linux-lts-trusty package in Ubuntu:
Invalid
Bug description:
I recently upgraded from 12.04 to 14.04. Afterwards, my system started
hanging randomly, sometimes after just a couple hours of use, and the
longest it went was about 32 hours. It's a full on freeze, not just X:
Ctrl+Alt+Fx does nothing. SysRq+REISUB does nothing. I've tried
tailing syslog and watching dmesg and there is nothing interesting
logged near the hang.
I ran memtest86+ two full passes, no errors.
Assuming maybe there was a problem with the installation or upgrade
process, I tried booting from a 14.04.1 USB (tried both 32-bit and
64-bit), and both hang after a few hours. I also tried stepping back,
using a 12.10 USB that I found and it also hangs.
Assuming it was related to newer kernel, I then tried to boot from a
brand new 12.04.5 USB (using the latest 3.13.0-32-generic kernel), and
the system did *NOT* hang... I ran it for five full days with no
problems before I rebooted to continue troubleshooting the problem --
so the newest 12.04 still seems good and the latest kernel seems good.
But something in 12.10 and beyond is bad.
I installed a crash-dump kernel and it doesn't seem to work - still
hangs and doesn't load the kernel.
I attempted to find help in the ubuntu forums, without much luck:
