After a reboot of the whole fabric (switches and machines), this problem
has not resurfaced. Conceivably this could have been a transient error
state, so I will close this with "invalid".

Public bug reported:
After upgrading 3 servers from linux-image-5.3.0-40-generic to linux-
image-5.4.0-48-generic I have started seeing the following queue
timeouts from IP-over-Infiniband (ipoib) devices. The devices in
question are (with newest available firmware, 2.42.5000):
# lspci -nnk -s
I have gotten the same kind of errors involving
"dcn20_setup_gsl_group_as_lock" function both with in-kernel and AMD's
own Pro driver. This happens every time when I run either a game or a
video player in fullscreen mode. Additionally any kind of monitor
screensaver or power saving mode will
I strongly agree with @andrewsomething here. Advertising has absolutely
no place in motd.

However, 4.10.0-24 does exist and gets installed with -edge. And it is

The MTU problem affecting OpenvSwitch bridges still exists (or
resurfaced) in linux-generic-hwe-16.04-edge (4.10.0.24.17).
# grep -i mtu /var/log/syslog

[...] lxcbr0: Invalid MTU 9000 requested, hw max 1500
Pretty please STOP BREAKING things.
Ok, so the fix is rather trivial. I've verified that building 4.10.0-22
kernel from Ubuntu sources with the following patch fixes the
OpenvSwitch MTU issue:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/openvswitch
4.10 series (hwe-edge) kernel doesn't seem to have gotten these fixes
yet, as 4.10.0-22-generic #24~16.04.1-Ubuntu still fails to set
openvswitch MTU correctly. When can we expect a fix to be released for
-edge?
