Thanks a lot for checking, Itai!
As discussed offline, we made another attempt with 5.19.0-28-generic
kernel and 22.35.2302 firmware on a different system, and also did not
run into this issue there.
Will set this to incomplete until we regain access to the system where
this was first observed so we can compare sw/hw components.
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete

This does not happen when using the Jammy 5.15 kernel, everything else
