Tested with 5.8.0-050800-generic downloaded from kernel ppa. Got exactly the same error as above, except this time the whole system froze and became unusable, so I had to kill the power to the PC.
Additionally I got a whole bunch of new errors in dmesg like [ 31.072963] SQUASHFS error: Unable to read metadata cache entry [31b7fff] [ 31.072964] SQUASHFS error: Unable to read directory block [31b7fff:13ee] which seem to be unrelated. ** Changed in: linux (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886234 Title: libvirtd Tainted: kobject_add_internal failed for emu10k1-synth-0-1 with -EEXIST, don't try to register things with the same name in the same directory.
