In your bug report, I see:
[ 32.029684] agpgart: Aperture conflicts with PCI mapping.
May 15 16:16:25 TheL kernel: [ 310.871291] NVRM: RmInitAdapter failed! (0x23:0xffffffff:679)
May 15 16:16:25 TheL kernel: [ 310.871311] NVRM: rm_init_adapter(0) failed
This looks like it might be a kernel or BIOS bug.
