I've now gotten the panic again with the callout:
Sleeping on "rtl8366rbstart" with the following non-sleepable locks =
held:
exclusive sleep mutex rtl8366rbcallout (rtl8366rbcallout) r =3D 0 =
(0x80769114) locked @ =
/home/stb/working/fe/stb-adrianchadd-freebsd-work/sys/kern/kern_mutex.c:14=
8

callout_init_mtx() says
> The usable lock classes are currently limited to mutexes and rwlocks, =
because callout handlers run in softclock swi, so they cannot sleep nor =
acquire sleepable locks like sx or lockmgr.

The way I read that, any callout will be run in a way that does not =
allow sleeping.  I'm not sure how to handle this.
