Hi there,
I wasn't sure which mailing list to use so I BCC'd intel-gfx@lists.freedesktop.org and dri-devel@lists.freedesktop.org
Just use Cc. We want all replies to go to the list(s) as well.
I'm using a Lenovo Thinkpad T470p and running the 4.19.77-1-lts kernel on Arch Linux. Recently, I've started getting freezes each day. Audio can still be heard, but video output stops. I was able to retrieve a call trace from journald.
I've attached the output of "sudo lspci -vvv" as well as the message from journald (null pointer dereference).

Looks like it could be https://bugs.freedesktop.org/show_bug.cgi?id=111381
in which case you just need to upgrade to 4.19.78 and it should be fixed.
