The kernel warning still shows up in 6.9.0-rc7. (I think 4 high load processes on a 2-Core VM could easily trigger the kernel warning.)
Thx for the report. Linus just reverted the commit 07ed11afb68 you mentioned in your initial mail (I put that quote in again, see above):
3628e0383dd349 ("Reapply "drm/qxl: simplify qxl_fence_wait"") https://git.kernel.org/torvalds/c/3628e0383dd349f02f882e612ab6184e4bb3dc10
So this hopefully should be history now.
Ciao, Thorsten
Since this affects the 6.8 series (6.8.7 and onwards), I made a CC to stable@vger.kernel.org

Ohh, good idea, I thought Linus had added a stable tag, but that is not the case. Adding Greg as well and making things explicit:
@Greg: you might want to add 3628e0383dd349 ("Reapply "drm/qxl: simplify qxl_fence_wait"") to all branches that received 07ed11afb68d94 ("Revert "drm/qxl: simplify qxl_fence_wait"") (which afaics went into v6.8.7, v6.6.28, v6.1.87, and v5.15.156).
Ciao, Thorsten
