Full dmesg from boot to error report, with drm.debug=0x1e set.
I am getting a General Protection Fault on 4.15-rc1, and the X11 screen
locks up within minutes of login, at every boot. Fault is still reproducible
in 4.15-rc6 at every boot. Previous kernels have all been fine.
file <kernel>: Linux kernel x86 boot executable bzImage, version 4.15.0-rc6
(mkeehan@babelfish) #11 SMP PREEMPT Mon Jan 1 13:11:17 GMT 2018, RO-rootFS,
swap_dev 0x4, Normal VGA
I use the Arch distribution, which is up to date as of today, Jan 1, 2018.
I use the xf86-video-intel, the i915 driver. Haven't tried nomodesetting yet.
I tried bisecting rc1, but found that some "good" bisections would hang up
after a few hours use. Whereas the hang occurred within minutes of booting rc1
itself.
The file /sys/class/drm/card0/error was empty. I used ssh into the locked up
laptop.
There is an nVidia chip present in this Dell Laptop XPS15, but I don't include
any nouveau driver in the kernel, nor the proprietary nVidia driver. There are
no bios options for video card selection or disabling.</pre>
