@guiverc this is not related to Ubuntu 19.10 or 19.04.
It was initially reported at that time, but it is still open.
I just stumbled on it, ugrading from 21 to 22.04.
Same behavior:
"error: out of memory.
Press any key to continue..."
Then kernel panic message.
I created a bootable USB image
For easier debugging this can be reproduced on any affected system
(Tried KVM and EC2) by just running:
$ sudo systemctl start hv-kvp-daemon.service
^^ This will stall while one would assume it should quick-exit due to
the ConditionVirtualization not being met.
A full cycle (90 second stall)
On a fresh AWS instance I already see it stalling on package install, I
do not even need to reboot :-/

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:

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).

I have tried the same again, this time with openvswitch unconfigured (but still
running).

chcpu disabling/enabling still crashes.
Ok, I have manually retried this - we do not need the KVM guest, it is the
chcpu that kills it.

ALSA: hda/cs8409: Remove unnecessary delays
BugLink:
Thanks for the advice. Unfortunately, the problem is still there.
I'm currently bisecting this on ubuntu-impish. So I've been booting
kernels back an forth and it keeps looking like a kernel issue to me. At
least the distro kernel is consitently broken while other kernels
consitently work.
--
Another observation:
In the broken configuration the audio output is initially detected as "internal
speaker" by gnome.
However, as soon as an attempt to access the speaker is made (play an alarm
sound, change volume) the device morphs into Headphones.

Hi Masato, I think I have re-discovered that with more detail in bug 1952246
Still waiting for the kernel team to look at.
** This bug has been marked a duplicate of bug 1952246
5.13 (I/J/F-HWE) Hosts
FYI this was reported earlier as bug 1944104 and still waits kernel team action
there.
Since this bug here has more data/details I've marked the other a dup.

Now that all data is in place I set it to confirmed to silence the bots.
@Kernel people - is this known, if so where? If it is not known what else would
you need here?
