This looks like a regression in the DRM code. I've added > suitable Ccs. Been running the box without loading ttm, drm, radeon modules (kernel 5.6-rc4) via ssh for two days now building stuff. Which worked flawlessly. With ttm, drm, radeon loaded I hit this bug within half an hour. So it really seems the drm code causing this bug.
Looks mostly the same on kernel 5.7-rc1. The line after kthread+0xd1/0xd3 is different. It was "? try_to_free_pages+0x3d4/0x3d4" on 5.5.6 and 5.6-rc4, but is "? shrink_node+0x6f2/0x6f2" on 5.7-rc1 now.

Can you bisect? If you are not actually using the GPU, I it shouldn't really be allocating any memory other than what it allocates for the console framebuffer and any driver structures. I think what may be happening is that you are hitting memory pressure and ttm is attempting to return memory and hits some failure.

It's an old i686 box of course, but it's new to me. The oldest kernel I ran this machine on is 5.5.6, the one for which I reported this bug. Older kernels won't boot it's btrfs root partition (xxhash, zstd compressed). So I have to do another install in an ext4 partition, replicate the setup and find a suitable starting point for bisecting.
Created attachment 289027 [details] bisect01.log Finally I finished bisecting. Criterion for a 'good' bisect run were successfully building llvm 5 times in a row. At 'bad' bisect runs the bug did show up at the 1st llvm build most of the time, rarely at the 2nd llvm build at the latest. It turned out the offending commit is also the cause of this org bug: https://gitlab.freedesktop.org/xorg/driver/xf86-video-ati/-/issues/191#note_489802 # git bisect good | tee -a ~/bisect01.log 33b3ad3788aba846fc8b9a065fe2685a0b64f713 is the first bad commit commit 33b3ad3788aba846fc8b9a065fe2685a0b64f713 Author: Christoph Hellwig <hch@lst.de> Date: Thu Aug 15 09:27:00 2019 +0200 drm/radeon: handle PCIe root ports with addressing limitations radeon uses a need_dma32 flag to indicate to the drm core that some allocations need to be done using GFP_DMA32, but it only checks the device addressing capabilities to make that decision. Unfortunately PCIe root ports that have limited addressing exist as well. Use the dma_addressing_limited instead to also take those into account.

Created attachment 290953 [details] revert does this revert fix the issue?
Does it work correctly with 5.9-rc1 or newer?
Another thing to try, does setting radeon.agpmode=-1 fix the issue?

Yes, I had the machine building with 5.9-rc2 for 2 days without issues. Though in my 5.9-rc .config I have not set AGP nor AGP_SIS 'cause it is no longer needed. I did not try building stuff with an affected kernel and radeon.agpmode=-1 yet. But I shall try and report back as soon as I have.

Yes, booting an affected kernel like 5.8.1 with radeon.agpmode=-1 also seems to fix the issue. Succesfully built llvm 10 times in a row which would normally crash the machine on the 2nd or 3rd build at the latest.
I'm hitting the same bug with kernel 5.9.14, same stack as the original comment. However I'm using the nouveau driver (so not radeon).

I'm also seeing a similar/related bug with nouveau and Kernels 5.10/5.11/5.12 X would freeze randomly (mouse and audio still working, then full crash). Things are fully stable with Kernel 5.4.

Closing here as the original issue on my machine was fixed back in 2020 and was connected to radeon/ttm modules. Apart from the issue taz.007 got with his card + nouveau driver the other "BUG: unable to handle page fault for address" likely have different origins. If your issues persist please read https://docs.kernel.org/admin-guide/reporting-issues.html#step-by-step-guide-how-to-report-issues-to-the-kernel-maintainers and open new bugs as stated there. If your are not running a vanilla kernel but a distribution kernel better report your problems to your Linux Distribution Maintainers first. ;)
