Created attachment 1631839 [details] kernel stack trace at console 1. Please describe the problem: Previously I was using Fedora 30 without problem. In Oct, around Oct-17. I had installed kernel 5.3.5-fc30 and used about one week without problem. Then I had upgraded to Fedora 31 with default (current) kernel 5.3.7-fc31. I had experienced at about one or two system freeze/crash since upgraded to FC31. I had also tried to use kernel 5.3.5-fc30 but still got a crash just now. When it freezes, there is no network connection. For the console, it is not accepting the magic sequence for the keyboard. I had enabled kdump but there is no core files generated. 2. What is the Version-Release number of the kernel: 5.3.5-200.fc30 and 5.3.7-200.fc31 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : 5.3.5-200.fc30 and 5.3.7-200.fc31 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Just use the desktop, it crashes randomly. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Haven't tried this because I am not sure if my GPU and vmware driver support the rawhide kernel. 6. Are you running any modules that not shipped with directly Fedora's kernel?: Nvidia and Vmware workstation. 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag.

When it freezes, there is no useful information logged in journalctl or /var/log/messages. In one occurrence of kernel freeze, it logged a few lines into system log but there no further useful information being logged: Oct 31 02:03:50 home kernel: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oct 31 02:03:50 home kernel: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oct 31 02:03:50 home kernel: #PF: supervisor read access in kernel mode Oct 31 02:03:50 home kernel: #PF: error_code(0x0000) - not-present page Oct 31 02:31:04 home kernel: microcode: microcode updated early to revision 0x43, date = 2019-03-01 The last line is from the manual system reboot after the system freezes
Just now I had updated to kernel 5.3.8 from update-testing. I tried to perform a CPU intensive task and the system hanged. Seems related to BFQ scheduler. Previously (FC30) I was using the deadline scheduler without problem.

I did try to move disk with system to another machine with the same CPU model (and moved GPU as that machine do not has it at all). Freezes continue. Memory was tested, all good. I see reports on system freez from users with AMD graphics but I have Nvidia one. It's very, very anoying to restart machine every 2-3 hours.
The main difference from #1: I have only one kind of workqueue entry for all freezes if present: "Workqueue: events key_garbage_collector". It can absent still (rare). May be I should make new BR?
Did you file a new BR? If so, I'll add my "me too" there.

*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 31 kernel bugs. Fedora 31 has now been rebased to 5.5.7-200.fc31. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 32, and are still experiencing this issue, please change the version to Fedora 32. If you experience different issues, please open a new bug report for those.
