            Bug ID: 104639
           Summary: kernel 4.15-rc8 reboots randomly with RX 560
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: peteralm1980@gmail.com

dmesg

My workstation running arch linux with a RX560 GPU randomly reboots after a few
minutes of use with the new amdgpu version in kernel 4.15. It seems to mostly
happen when there's a full screen redraw happening (such as maximizing a
window.) It happens regardless of desktop environment (I've tested GNOME on
both wayland and Xorg, as well as KDE). If it's left at the GDM login screen it
doesn't seem to reboot.

Kernel version 4.14 and older seems to be rock solid.

I've tried the following things to workaround it but nothing seems to make any
difference:
 * Setting amdgpu.dc to both 1 and 0

 * Disabling dpm by setting amdgpu.dpm to 0

 * Upgrading MESA from 17.3.2 to latest git master

Can you try bisecting? Make sure to test each commit for plenty of time before
marking it as good.

Hi Michel,

After bisecting it seems as the offending commit seems to be:

commit 648bc3574716400acc06f99915815f80d9563783
Author: Christian König <christian.koenig@amd.com>

    drm/ttm: add transparent huge page support for DMA allocations v2

    Try to allocate huge pages when it makes sense.

    v2: fix comment and use ifdef

After reverting that 4.15-rc8 seems to be working fine.

Does your kernel also have the following patch?

    drm/ttm: don't use compound pages for now

    We need to figure out first how to correctly map them into the CPU page
tables.

Sorry, just seen that you wrote that you are using 4-15-rc8 and that should
include the patch.

No idea what's going wrong here. You not by any chance could add a
serial/network console and grab the last logs before the reboot?

Christian,

These are the last messages from a network console. All of them are from before
the crash:

I don't have a serial dongle here so I can't use a serial console but at one
point I ran the console on the integrated intel GPU (I usually have it disabled
in BIOS) while using Xorg on the AMD GPU, there was no messages there either. 

If you come up with any ideas or patches I'm happy to try them out.

Do not use mainline kernels and point releases Mesa. They work randomly as you
see because of partially implemented drivers. Use the kernel below and Mesa dev
git. Debian testing/sid Xfce is easier and more stable than Arch Linux with
never ready buggy desktops kde and gnome. Oibaf Mesa git ppa bionic version is
compatible with Debian testing/sid.

https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.17-wip 

No problems with my RX560 with latest code.
