yet it is still reproducible for me on 4.16-rc7 and 4.16.0, which already
have your fix. I don't know about earlier versions -- my newer card went
into flames just a few days ago, and I replaced it a brand new 8400GS (G98)
I happened to have in a dusty closet. Obviously, I can bisect if that would
be helpful, but the error looks the same thus I'm reporting first.

Artifacts are not correlated with any printk-ed errors; somehow of my two
monitors they ever happen only on the left small one (via DVI) but not on
the right big one (via HDMI, xrandred vertical). A screenshot:
https://angband.pl/tmp/g98-artifacts.png
These never happen on initial draw, slowly appear and accumulate,
disappearing once the window is redrawn, then start appearing again.
Crash (only one happened so far):

Unfortunately I will not be able to help you, as patch fixed issue on
my system and thus I have no means to test anything more. My card is
G98M [Quadro NVS 160M]. Besides – I'm a geographer not a programmer
;-)
Still your report makes to question the original commit I was fixing
(mmu: swap out round for ALIGN). Could you test if going back to
rounddown fixes problem on your side?

And I'm, it seems, servant of a particular cat, all else being secondary. :p

I did not observe a TRAP_M2MF, but the above were present in previous

These, as I call them, 406040 errors, have been around on Tesla for
ages. We have no idea what leads to them, but generally some kind of
fifo desync appears to follow.

Taking this into account, going back to rounddonw from ALIGN_DOWN
seems to fix breakage on some systems. Lets wait for Ben's input on
this matter, as he swapped rounddown with ALIGN_DOWN to fix some kind
of build problems on 32bit systems.
Ilia, is there anything we could add to our kernels to shed some light
on 406040 errors? I am not certain if I have seen those on my
hardware, but, as you say, they might be rare enough to not remember
it.
Māris.
