When qat(4) is loaded from from loader.conf(5) on FreeBSD

during boot. No dump or backtrace available, only recording from IPMI console
where these messages precede the panic:

qat0: disabling second AE
panic: timed sleep before timers are working

To reproduce please add these to /boot/loader.conf on the system with Atom

cryptodev_load="YES"
qat_load="YES"
qat_c2xxxfw_load="YES"
