There are three bugs here:
- We need to call unpopulate() if ttm_tt_populate() succeeds.
- The "new_man = ttm_manager_type(bdev, bo->mem.mem_type);" assignment was wrong and it was really assigning "new_mem = old_mem;". There is no need for this assignment anyway as we already have the value for "new_mem".
- The (!new_man->use_tt) condition is reversed.

This is from reading the code and I can't swear that I have understood it correctly. My nouveau driver is currently unusable and this patch has not helped. But hopefully if I fix enough bugs eventually it will start to work.
Well NAK, the code previously looked quite well and you are breaking it now.
What's the problem with nouveau?
The new Firefox seems to excersize nouveau more than the old one so when I start 10 firefox windows it just hangs the graphics.
I've added debug code and it seems like the problem is that nv50_mem_new() is failing.
Sounds like it is running out of memory to me.
Do you have a dmesg?
At first there was a very straight forward use after free bug which I fixed. https://lore.kernel.org/nouveau/YMinJwpIei9n1Pn1@mwanda/T/#u
But now the use after free is gone the only thing in dmesg is: "[TTM] Buffer eviction failed". And I have some firmware missing.

The eviction failed message only shows up a minute after the hang so it seems more like a symptom than a root cause.
Yeah, look at the timing. What happens is that the buffer eviction timed out because the hardware is locked up.
No idea what that could be. It might not even be kernel related at all.
I don't think it's hardware related... Using an old version of firefox "fixes" the problem. I downloaded the firmware so that's not the issue. Here's the dmesg load info with the new firmware.
