Title:
watchdog: BUG: soft lockup - CPU#7 stuck for 22s! [kworker/7:2:729]
Status in linux package in Ubuntu:
Incomplete
Bug description:
Since doing a fresh install of 18.04 Beta, I experience random lock-
ups. Also, running Neofetch causes what looks like a hard lock, but
the screen continues to refresh (system monitor continues to display
new data). However, inputs don't work (mouse and keyboard). Not sure
if this is related.
