Start happening to me now on boot when I connect to docking station (which brings secondary monitor) 4.10.0-35-generic #39~16.04.1-Ubuntu SMP Wed Sep 13 09:02:42 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
After reading this thread I realised that its probably multiple problem of dead lock which trigger the watchdog message but causes are different, it could be one bug in kernel or could be multiple problems all resulting in dead lock. I actually always had reboot problem - it locked up on reboot, but I ignored it, but now it does not boot at all which is more of an issue. So I have to apply 2 solutions: - for shutdown issue I apply fstab fix from #72, now it shuts down properly, but hang still happens on boot when attached to secondary monitor - for booting issue I switch from nouveau display driver to Nvidia 375.66 and it seems to work now (it could be that I just stop hitting it temporary and it really triggered by random race condition) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1530405 Title: NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s!
