NetBSD 9.99.18 NetBSD 99.99.18 (GENERIC) #0: Sat Nov 23 14:50:58 EST 2019 
>Description:
I'm running a custom compiled NetBSD-current on a very lightweight x64 box (2GB RAM, 2 core AMD E-2100 CPU, etc.) The sources I compiled from were the current tar files as of 10/23/2019

The system has two network interfaces . One is a Realtek ethernet adapter powered by the re driver and the other a Realtek wireless card powered by the rtwn driver.

I was going to bring the ethernet interface up, but wasn't paying attention and accidentally typed the name of the other interface so: `ifconfig rtwn0 up`. After entering that, the system froze for a second before rebooting. Upon rebooting, the kernel panics with the following:

    `[ 56.6326531] panic kernel diagnostic assertion "(!cpu_intr_p() && !cpu_softintr_p()) || (pc->pc_pool.pr_ipl != IPL_NONE || cold || panicstr != NULL)" failed: file "/path/to/kernel/source/sys/kern/subr_pool.c" line 2553 pool_cache_get_addr: [pnbufpl] is IPL_NONE, but called from interrupt context` 

And then gets stuck in a reboot loop. With that same panic every time. I can escape the boot loop in single user mode, but am not sure what to do from there.
>How-To-Repeat:
Not quite sure exactly how reproducible it is. As stated before, the initial crash was caused by running `ifconfig rtwn0 up`
