Good day.

I found that xen_panic_event (in arch/x86/xen/enlighten.c) ignore sysctl
settings for kernel.panic, which declare delay between crash and crash
consequences. 

F.e. if we do this in:

sysctl kernel.panic=30
echo c >/proc/sysrq-trigger

I expect at least 30s of crashdump on screen, not instant domain
disappearance.

Is this feature or bug?

Thanks.
