Subcases below still failed on latest -nightly(08ce6614d07dd1e426109672a5e323317c8d6ec7) gem_evict_alignment_minor-interruptible gem_evict_alignment_minor-normal Swap is still available. Requires invalidate patches from bug 72742 Sounds like a dupe of the filp leak ... Please retest and reopen if it still happens. Nevermind, got lost. Created attachment 100340 [details]
