I just (re-)installed Ubuntu on my workstation, and I’m having trouble with getting a bunch of “Ubuntu experienced an internal error” messages on boot. When I look into the underlying error message I see:
watchdog: BUG: soft lockup - CPU#10 stuck for 22s! [Xorg:1431]
Nothing super terrible seems to happen, but sometimes I get them one after another for a couple minutes.
I’ve googled around and there seems to be a bug with a similar error message where users can’t boot into ubuntu when using nvidia + the nouveau drivers, but I’m using the nvidia proprietary drivers, and even before I install them, my machine boots.
I’ve reinstalled Ubuntu a couple times, but it always comes back. Usually, Ill be able to boot the machine fine like 3 times (as I’m installing all my software) before it sets in.
I thought it might have to do with setting screen scaling to something other than 100%, but I’ve also experienced it with no screen scaling at all.
I’m considering switching to an AMD card for my video out, I’ll report back if that changes anything.
