PROBLEM: random desktop freezes, kmsg errors "Failed to parse relocation -12" and "failed to pin new rbo buffer before flip"

[Lucas Werkmeister]

Hi all,

on Linux 5.11.1 and 5.11.2 (but not 5.10.16), my Gnome desktop (Radeon
R7 260X GPU) occasionally (usually after a few hours) freezes
completely; when it happens, I can still switch to a TTY (Ctrl+Alt+F3)
and back to the frozen desktop (Ctrl+Alt+F2), but I haven’t found a way
to “rescue” the desktop from the command line, and ultimately have to
reboot. When that happens, the journal is filled with many copies of
these kernel messages:

> [drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to parse relocation -12!

> radeon 0000:01:00.0: 00000000641f4713 pin failed

> [drm:radeon_crtc_page_flip_target [radeon]] *ERROR* failed to pin new
> rbo buffer before flip

I have uploaded the kernel logs of one affected boot, in systemd journal
export format, at <https://tmp.lucaswerkmeister.de/radeon-freezes.jnle>.

Kernel version:
$ cat /proc/version
Linux version 5.11.2-arch1-1 (linux at archlinux) (gcc (GCC) 10.2.0, GNU ld
(GNU Binutils) 2.36.1) #1 SMP PREEMPT Fri, 26 Feb 2021 18:26:41 +0000

Kernel .config file (from /proc/config.gz):
<https://tmp.lucaswerkmeister.de/radeon-freezes.config>

Most recent kernel version which did not have the bug: 5.10.16 [though
this has a similar issue, where the desktop also freezes but then
unfreezes either on its own or when I switch to a TTY and back; I
haven’t reported this yet, and don’t know if it’s related or not]

I have not yet found a way to systematically reproduce this. It seems to
happen more frequently when there is more load on the system, or on the
graphics card (e.g. fullscreen video playback, desktop recording).

I can’t think of any other relevant information at the moment, but I’ll
be happy to respond to any questions you have. If you come up with a
patch, I think I should be able to test it, though admittedly it’s been
a few years since I’ve built a kernel.

Cheers,
