Yes we have overlapping virtual address ranges for kernel and user space and user
space registers are stored at the start of the kernel stack.

But I am not sure, if that is the reason here (have to verify this).

Doesn't the -t option check all the stack memory and looks for valid symbol
addresses? So IMO everything found there could be by chance the address
of panic. Why is this no problem on x86?
