Public bug reported: 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.
