--- Comment #3 from Alexander Ziaee <ziaee@FreeBSD.org> ---
Reproduced on the latest current snapshot (kernel 1500043) on Atom C3558. If
kldloading qat, it loads the firmware. However, if specifying qat in
loader.conf, it panics during early boot attempting to load the firmware:

qat0: <Intel c3xxx QuickAssist> mem 0x80c00000-0x80c3ffff,0x80c40000-0x80c7ffff
at device 0.0 on pci1
qat_c3xxx_fw: could not load firmware image, error 6
