I've a PERC H700 and a recent NetBSD-6.0_STABLE kernel (from yesterday). But 
even after creating /dev/mfi0 and /emul/linux/proc/devices, MegaCli didn't see 
any adapter.


From ktrace, no problem on megaraid_sas_ioctl but it seems to fail on 
/sys/class/scsi_host:

Any advice ? This tools will be a big help for my uptime :-)

thank you.
