I unmounted proc and /emul/linux/proc/devices now looks like:

Character devices:
205 megaraid_sas_ioctl


mfi0 was created with: /usr/pkg/emul/linux/bin/mknod -m 600 mfi0 c 205 0

/emul/linux/proc/dev listing:

cr--------   1 root  wheel  - 205, 0 Nov  8 17:05 megaraid_sas_ioctl_node
crw-------   1 root  wheel  - 205, 0 Nov  8 17:07 mfi0


(the ioctl_node file appears when I run MegaCli64)


But still, no adapters detected:

# ./MegaCli64 -AdpAllInfo -aALL

Exit Code: 0x00


ktrace has this to add:
