After upgrading to kernel 5.14, I get the following kernel crash. This seems to be related to the RME HDSPe Multiface II audio interface. Other people are also reporting this bug for RME audio interfaces.

Can you try this patch against the latest 5.14.X kernel which is 5.14.16 as of this writing https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=cbea6e5a7772b7a5b80baa8f98fd77853487fd2a
I was able to fix the problem with these two patches from https://www.spinics.net/lists/alsa-devel/msg129824.html ALSA: pcm: Check mmap capability of runtime dma buffer at first ALSA: pci: rme: Set up buffer type properly

Can you try this patch? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=cbea6e5a7772b7a5b80baa8f98fd77853487fd2a

upstream has a new patch, see https://bugzilla.kernel.org/show_bug.cgi?id=214947
Is this one patch all we need?
(In reply to Mike Pagano from comment #8) > Is this one patch all we need? yes, it replaces all other patches
