[Bug 1562618] Re: whole OS freezes seemingly randomly
The 4.4.0-16 kernel gave me a freeze too recently. Ran really long
without issues but on a next boot after testing the 4.6.0-rc2 it froze.
So I am basically back to where I was when I reported this, with the difference that the BIOS is the latest now.
I am not sure how to continue troubleshooting in the best way.
I am wondering if this can be a hardware issue and if it may have happened before the 16.04 update too, or that I just got lucky.
Given the unexpected conditions of the freeze (last time it was not during some download action) it is very hard to determine the cause.
Can anyone advise on what to do next?
I could try a pre 4.2 kernel or install windows to try and see if this keeps happening.
If anyone has a better idea, please let me know.
Would be great to be able to use the machine again with Linux running reliably.
