To be as precise as I can at present, this appeared somewhere between
these two Fedora kernel package builds:
Package: kernel-4.15.0-0.rc0.git6.1.fc28
Old package: kernel-4.15.0-0.rc0.git3.1.fc28
(that is, 'git3' did not have the issue, 'git6' does). Laura could
translate that to a delta that'd mean more to you folks, I expect.

To be as precise as I can at present, this appeared somewhere between
these two Fedora kernel package builds:
Package: kernel-4.15.0-0.rc0.git6.1.fc28
Old package: kernel-4.15.0-0.rc0.git3.1.fc28
(that is, 'git3' did not have the issue, 'git6' does). Laura could
translate that to a delta that'd mean more to you folks, I expect.

Looks like a TTM regression due to:
0284f1ead87463bc17cf5e81a24fc65c052486f3
drm/ttm: add transparent huge page support for cached allocations v2
If the driver requests dma32 pages, we can end up trying to alloc huge
dma32 pages which triggers the oops. The bochs driver always requests
dma32 here.
I'll send a rough patch once I boot it.
Dave.

Looks like a TTM regression due to:
0284f1ead87463bc17cf5e81a24fc65c052486f3
drm/ttm: add transparent huge page support for cached allocations v2
If the driver requests dma32 pages, we can end up trying to alloc huge
dma32 pages which triggers the oops. The bochs driver always requests
dma32 here.
I'll send a rough patch once I boot it.
Dave.

Hi Dave,
fyi only: It looks like this is not the only regression in this cycle
with ttm, novueau seems to suffer as well [1].

Hi Christian,
no problem, rc1 isn't even released, so hitting bugs is expected! Yet
Daves fix ("drm/ttm: don't attempt to use hugepages if dma32 requested
(v2)" [1]) is not enough to fix the problem and a similiar backtrace to
the one posted below in my first replay to this thread can be observed
with Daves patch applied [2].
Greetings,
Tobias
