<pre>I consistently experience complete system crashes when browsing web pages using
firefox for about 30 minutes, with the following dmesg output from the amdgpu
driver:
[ 2330.720711] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout,
last signaled seq=40778, last emitted seq=40780
[ 2330.720768] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma1 timeout,
last signaled seq=31305, last emitted seq=31306
[ 2330.720771] [drm] IP block:gmc_v8_0 is hung!
[ 2330.720774] [drm] IP block:gmc_v8_0 is hung!
[ 2330.720775] [drm] IP block:sdma_v3_0 is hung!
[ 2330.720778] [drm] IP block:sdma_v3_0 is hung!
(Above cited messages are the last to make it to a network-filesystem by
running "dmesg -w" before the system stops to do anything.)
I am running a kernel compiled from
<a href="https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next">https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next</a> as of
"commit 94097b0f7f1bfa54b3b1f8b0d74bbd271a0564e4" (so the very latest as of
today).
My GPU is an RX 460.
Notice that this bug may be the same symptom as reported in

title="NEW - amdgpu: [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout, [drm] IP block:5 is hang"
href="show_bug.cgi?id=98874">https://bugs.freedesktop.org/show_bug.cgi?id=98874</a>
However, the system crashes for me occur usually while vertically scrolling
through some (ordinary) web page.</pre>
