I had chrome, slack and vmware-player running in Gnome. While doing some git clone, screen+mouse+keyboard froze for 2 minutes after which xorg and everything else recovered. I saw this in dmesg: kernel: show_signal_msg: 2 callbacks suppressed kernel: GpuWatchdog[20399]: segfault at 0 ip 0000556fd1665ded sp 00007efbf17e46c0 error 6 in chrome[556fcd72a000+7171000] kernel: Code: 48 c1 c9 03 48 81 f9 af 00 00 00 0f 87 c9 00 00 00 48 8d 15 a9 5a 9c fb f6 04 11 20 0f 84 b8 00 00 00 be 01 00 00 00 ff 50 30 <c7> 04 25 00 00 00 00 37 13 00 00 c6 05 c1 6d kernel: nvme nvme0: I/O 202 QID 6 timeout, aborting kernel: nvme nvme0: I/O 203 QID 6 timeout, aborting kernel: nvme nvme0: I/O 204 QID 6 timeout, aborting kernel: nvme nvme0: I/O 205 QID 6 timeout, aborting kernel: nvme nvme0: Abort status: 0x0 kernel: nvme nvme0: Abort status: 0x0 kernel: nvme nvme0: Abort status: 0x0 kernel: nvme nvme0: Abort status: 0x0 kernel: nvme nvme0: I/O 202 QID 6 timeout, reset controller kernel: nvme nvme0: 12/0/0 default/read/poll queues While writing this bug report, the system froze again, and this time it didn't recover. After a cold reset I didn't see any other GpuWatchdog messages in journalctl. Ubuntu applied a BIOS firmware update before the first freeze, so my BIOS was updated as part of the cold reset I did. Not sure if this is relevant to reproducing the freeze.
