A few days ago, I upgraded to 17.04. Since then, roughly once a day, my computer locks up. These crashes occur in two ways: * While actively using the machine, Xorg locks up a CPU. * I leave the computer idle overnight, and the display won't wake up to the lock screen. Nothing responds at all; I can't switch to tty1 to reboot either--I have to manually kill the power. I found most of the relevant errors in my syslog; all but one say "Comm: Xorg Tainted". So, is this a known issue? Xorg bug? Kernel bug? Are these even the same bug? Let me know what other info I can provide! -----CPU Lockup #1----- May 23 17:51:12 kernel: [68524.881702] NMI watchdog: BUG: soft lockup - CPU#2 stuck for 22s!
