This is actually fixed already in 5.13.0.39.44 as shown above, but the root cause that I'm facing is that edge-Kernel is behind non -egde: $ rmadison -a amd64 -u ubuntu linux-image-generic-hwe-20.04-edge | grep focal linux-image-generic-hwe-20.04-edge | 5.13.0.27.29~20.04.13 | focal-security |

FYI for a different test I upgraded the system to Impish and on the 5.13.0-39-generic there neither of the two kernel bugs happens. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1966870

I tried things once more, this time OVS wasn't active at all (in the former try it was active after boot and then disabled) - still failing. Next I tried to use a different kernel(5.4.0-105-generic) I don't know when in >5.4 this started to fail, it surely worked a few months ago already using

As the last stage in the crash is in ? blk_mq_exit_hctx+0x160/0x160 I was looking if there was anything else with block devices going on. I found another crash right at boot/init time (this one is also in the attached currentDmesg.txt). [ 537.566942] [ cut here ] [
