--- Comment #37 from Ievgen Popovych (jmennius@gmail.com) ---
So I was trying to reproduce, kept the trace running for a few days or more,
but then it never happened and I've stopped tracing.
Now it happened again, on Fedora kernel 5.17.11, when waking up from suspend.
As I am looking though the logs there were total of 4 occurrences of "Reading
Intel version command failed", but I think only today I've noticed BT not
working and having to do the rmmod dance (few times to fix it).
