>Description:

Trying to boot a kernel with

options PAE

causes an immediate reset while the kernel is booting, the last message I could see before the screen went dark was at configuring ichsmb0.

The same kernel without PAE works fine.

cpu0: "Intel(R) Celeron(R) CPU  N3150  @ 1.60GHz"
cpu0: Intel Atom X[57]-Z8000 (Airmont) (686-class), 1600.25 MHz
cpu0: family 0x6 model 0x4c stepping 0x3 (id 0x406c3)
cpu0: features 0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE>

>How-To-Repeat:

Try to boot a PAE kernel.
