Kernel panics with recent 4.9 Kernels

hi all,

with Kernel 4.9.150, I sometimes have "kernel panic - not syncing: Fatal 
exception in interrupt" on two different servers. Dunno how to reproduce but
may be connected to high network traffic. Find screenshots, config.txt and
boot.msg here: https://www.netestate.de/kernel_panic/

cu,
brunni

I'd suggest trying to capture events with something better than an
incomplete screenshot, ie serial console, netconsole, anything that
will let you show the full event and a few lines leading up to it.

P.S. CONFIG_PRINTK_TIME improves log quality as well.
