It's some GPU hang that leads to the real kernel crash.... which happened on others sometimes, too. Unfortunately there is no fix for this and likely not for Leap 15.2 kernel.
Could you try the kernel in OBS Kernel:stable or SLE15-SP3 kernel in OBS Kernel:SLE15-SP3? 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.

That's bad. Do you have the secure boot enabled? If so, disable it when you test a kernel from OBS repo that is other than the official release.
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.
