Comment 0 for bug 2043640

I've been using 23.04 for a few months, and experienced a total system hang occasionally when sharing my screen over Zoom or Google Meet (running on Google Chrome).

At first it hangs and then it periodically flashes like it's trying (unsuccessfully) to recover; I've got 3 screens (including the laptop's internal one) and each attempt shows something different (at first it tries to recover the contents of all 3 screens, then it shows only one of them, and then it shows the same content on all 3, but it never gets responsive).

I've recently upgraded to 23.10, hoping a new kernel would help the situation. It's only gotten considerably worse now; it hangs sometimes just when opening Zoom; it's somehow easier to reproduce with Google Chrome. Interestingly, it fails quickly and reliably now when enabling my webcam (with special effects). It started hanging badly when using Google Maps as well.

For all these behaviors, I suspect amdgpu is to blame (I'm running on Renoir, 4750U Pro); `dmesg` and `journalctl` didn't seem to show anything interesting.

Any tips about debugging this further?
