Hi,
This is your friendly bug reporter.
The environment is vanilla torvalds tree kernel on Ubuntu 22.04 LTS and a Ryzen 7950X box.
Please find attached the complete dmesg output from the ring buffer and lshw output.
NOTE: The kernel reports tainted kernel, but to my knowledge there are no proprietary (G) modules,
but this taint is turned on by the previous bugs.
