Hello,
when trying to execute a remote firefox (from a debian based system) via
ssh(1) the kernel panics immediately.
Executing xlock(1) from the same remote system does not trigger the panic.
The kernel is a
13.0-CURRENT #1 r356122M: Fri Dec 27 14:55:13 CET 2019
root@myhost:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG
and the panic backtrace is always like
panic: page fault
cpuid = 2
time = 1577461608
