Hello,
We just started testing on 6.2, and hit the crash below. We have some modest changes to ax210 radio,
so could be us... Curious if anyone has seen similar?
I guess 'pkt' is corrupted?
And for what its worth, I am pretty sure we have seen something similar on older kernels,
though rarely.
general protection fault, probably for non-canonical address 0x5088000000000: 0P
