Thank you for your report. We're not aware of any major issue affecting the virtualization stack distributed with Ubuntu Focal: if it was broken as badly as you describe we'd be certainly receiving many bug report about it. This is not to easily dismiss your bug report as "not a bug, local corruption", but to explain that at this stage, if that's actually a bug, it somehow affects your specific system or configuration. This said, there isn't really enough information here for a developer to confirm this issue is a bug, or to begin working on it, so I am marking this bug Incomplete for now.
If you can provide exact steps so that a developer can reproduce the original problem, then please add them to this bug and change the status back to New. Personally I'd start the debugging with a full test of the system RAM. The boot loader menu of the Ubuntu ISO images offer an option to perform such a check. ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915627 Title: Windows 10 BSOD and Ubuntu 20.04.2 VM kernel panic on kernel 5.8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1915627/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
