>Description:
Upon issuing 'gmirror load' I get:
GEOM_MIRROR: <blah>
GEOM_MIRROR: Device /dev/ad4 activated
GEOM_MIRROR: Device /dev/ad6 activated
(slight pause)
Fatal double trap:
eip = 0xc4f36fed
esp = 0xe35d4ff4
ebp = 0xe35d5030
cpuid = 0; apic id 03
Previous to this I have created a gmirror across 250GB HDDs hanging off a Silicon Image 3112 controller. It's an SMP box with an SMP kernel, and the problem is reproducible.
