dmesg memory error for NVIDIA

snovik · 2017-10-20 11:37:59

I have this dmesg error:

pci 0000:03:00.0: BAR 6: failed to assign [mem size 0x00080000 pref]

Also my system hangs on heavy memory load (does not swap even though swap is enabled).

Is it fixable?

Do you also have sth. like "disabling [mem 0xfffff000-0xffffffff] because it overlaps 0000:03:00.0 BAR 6 [mem 0xfff80000-0xffffffff pref]" (where the memory areas can oc. differ)?

Does not seem so

(likely) BIOS bug and the kernel fails to work around it, see https://lists.gt.net/linux/kernel/2265600

Since this is an optimus system, how did you set it up?
Do you get the OOM knock-out even w/o the nvidia driver loaded (bumblebee setup and no client on the GPU)?
