Which kernel version is supported by up2 6000?

I am using ubuntu 20.04 with the following kernel:

Linux up 5.13.0-rt1 #1 SMP PREEMPT_RT Thu Oct 27 10:42:06 CEST 2022 x86_64 x86_64 x86_64 GNU/Linux

I am compiling the kernel 5.13 from this branch patched with this PREEMPT_RT patch patches-5.13-rt1.tar.gz.

However sometimes the kernel crashes

Here you can find the configuration used for compiling the kernel some logs I could get from a crash (not sure if it's related to the image).

Why is it happening?
Do you have any hint on which kernel version will work with RT patch on the up2 6000?

Thank you
