5.1.15 kconfig
On recent kernels (at least since 5.1.15), video playback will (sometimes) hard
reset my POWER9 system with an AMD RX 580. Due to the nature of the crash, it
does not seem that any kernel logs are produced by the event. The system
Hostboot firmware does record the crash though, and it produces a GUARD event
which disables the CPU slice the crash occurred on for subsequent boots until
it is cleared.
An upstream Hostboot issue has been submitted by another person who has
encountered this behavior as well:
https://github.com/open-power/hostboot/issues/180
I have been unable to reproduce the issue on kernel 5.0.9, indicating a
regression somewhere in between.
Attached is my 5.1.15 kernel config, the output of lspci -vv, and the contents
of /proc/cpuinfo.
