Nouveau dmem NULL Pointer deref (SVM)
Hi,
just for your information and maybe for some help: with 5.1rc1 and SVM
enabled i see the following backtrace [1] when the nouveau card (reverse
prime) goes to sleep, for now i have papered over with [2] which leaves
me with userspace hangs. Any pointers where to look for the actual culprit?
PS: Card is: nouveau 0000:01:00.0: NVIDIA GP106 (136000a1)
Greetings,
Tobias
