After realizing the uncore lock only needed to be converted to a raw spinlock because the testcase was broken, I tested the alternative fix of using sleeping context only in the selftests: https://patchwork.freedesktop.org/patch/707063/?series=162145&rev=1 With that the reset selftest works as expected. But I do see some weird lockdep splats and aborts after that fixed the uncore lock testcases: https://patchwork.freedesktop.org/series/162145/ I believe it could be a different instance of: https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_162145v1/bat-dg2-9/igt@[email protected]#dmesg-warnings904 Which is tracked under: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/15759 Perhaps those are related to what you are seeing? Also don't use that series for anything but CI results, I rather want to submit a new version of this series. Kind regards, ~Maarten Lankhorst
