No? Well, it was the regression that bothered me most. But there are still a few out there that got introduced this cycle. There is a regression in RDMA/mlx5 introduced in v5.16-rc5: https://lore.kernel.org/lkml/f298db4ec5fdf7a2d1d166ca2f66020fd9397e5c.1640079962.git.leonro@nvidia.com/ https://lore.kernel.org/all/EEBA2D1C-F29C-4237-901C-587B60CEE113@oracle.com/ A fix is available, but got stuck afaics: https://lore.kernel.org/lkml/f298db4ec5fdf7a2d1d166ca2f66020fd9397e5c.1640079962.git.leonro@nvidia.com/ And I only noticed just now: a revert was also discussed, but not performed: https://lore.kernel.org/all/20211222101312.1358616-1-maorg@nvidia.com/ Will let Greg know, seems the commit got backported to 5.15. s0ix suspend broke for some AMD machines, Alex and Mario are busy looking into it: https://gitlab.freedesktop.org/drm/amd/-/issues/1821 https://bugzilla.kernel.org/show_bug.cgi?id=215436 Alex is also dealing with another issue where the screen contents now get restored after some input events: https://bugzilla.kernel.org/show_bug.cgi?id=215203 There still seems to be a performance regression that Josef and Valentin try hard to pin down without much success for weeks now: https://lore.kernel.org/lkml/87tuf07hdk.mognet@arm.com/ And there one more report, but it might be a follow-up error due to another regression: https://lore.kernel.org/linux-pm/52933493.dBzk7ret6Y@geek500/
