ServeRAID-6M via ips.ko. DragonFly_Stable sources as of yesterday. When I issued halt I got plenty of screens of these:
ips0: flushing cache
Dump already in progress, bailing...
Shutting down ACPI
panic: trying to free NULL pointer
mp_lock = 00000001; cpuid = 0; lapic.id = 00000000
boot() called on cpu#0
Uptime: 6h40m15s
Now it just waits there and keyboard is dead.
