kernel BUG dmesg 1

I've been getting occasional graphics lockups, fixable only by reboot. I was hard rebooting until I realized I could ssh in to my desktop still, so here are two dmesg logs that I've captured. There's also a report of (I think) this same bug in the LKML: https://lkml.org/lkml/2020/12/31/47

If it's the same issue, it's fixed with these patches:

OK, thanks. I've sometimes used the whole graphics stack built from source; I'll do it again, using the latest drm, and see if that fixes it.

It was happening regularly to me previously, but now using DRM master I haven't seen it happen once. Looks like you were right about it being fixed in those patches.

Thanks!
