Hello Greg,
from kernel-4.9.270 up until now (4.9.282) I experience kernel crashes upon loading a GPU module. It happens on two out of at least six different machines. I can't believe that I'm the only one where that happens, but since the bug is still there twelve versions later, I need to report this.
I run Gentoo with vanilla kernels. Upon loading i915.ko (automatically or manually) my laptop freezes until power-down. (Note that other machines using i915.ko have no problems here.) It's an Asus laptop with Intel chipset with a peculiarity:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02) 01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940MX] (rev a2)
(It uses Intel natively and nobody knows how to make use of that Nvidia chip)
On an AMD desktop I get the same crash upon loading of nouveau.ko .
Something ugly must have been introduced in kernel-4.9.270 . Strace modprobe .. only prints two lines on the screen. Strace modprobe .. 2>&1 > file produces only an empty file.
Any ideas?
