The latter contains the backport of DRM stack up to 5.9.x. I've been testing kernel 5.10.6-3.g183dcff-default of Kernel:stable for almost 14 days now, not a single crash.

I'm on kernel 5.3.18-107.g0b709ea-default of Kernel:SLE15-SP3 now, it works for me. Didn't change anything about secure boot, though, I don't think I had it enabled. I'll report back when in another 2 weeks if it won't crash sooner.
