Hi,
In order to investigate bug LP#1531768, we upgraded some arm64 compute
nodes (swirlices) to a 4.4 kernel. I think it made the VMs work better,
but the hosts became extremely unstable.
After some time, getting a shell on them would be impossible. Connecting
on the VSP,
Hi,
I'm sorry but 4.4 is too unstable on the hosts. We have to reboot and/or
power cycle them multiple times a day. We're back on 4.2 everywhere.
Haw gathered some perf data on a failing 4.4 host, perhaps we can start
digging the issue from here ? Perhaps it should be a separate bug as
well.

Re-reading comment #318 Dan, I realize that we may be investigating a
symptom and not the root cause.
Whenever the soft-lockup happens, the serial console does get flooded
"block nbdX: Attempted send on closed socket". If the serial console
getting flooded causes soft lockups, then it is indeed a
Hi Dan,
Thanks for your investigation. Sorry for the delay, but finally I
managed to reboot the compute nodes with the "notsc" kernel parameter. I
also disabled the qemu-nbd workaround.
Once that was done, it didn't take long for a node to crash, which would
indicate that notsc didn't fix the

and a few "CPU soft lockup" messages (see attached log). This clears up
