Bug description:
Hi, the IRC guys suggested to file a bug here with 'linux'.
# cat /proc/version_signature
Ubuntu 5.15.0-46.49-generic 5.15.39
Description: Ubuntu 22.04.1 LTS
Release: 22.04
I'm not able to attach the lspci output - but it's happening on various
hardware flavors (intel i350 nic, mellanox connectx-6, xeon/epyc cpu's, etc) so
it doesn't look hardware related. If you want to know something hardware
specific let me know.
