Hi,

i have 2 machines, both are equipped with a symbios 53c875 controller. 
Both controllers connect to the hostchannel of a cmd 5440. (Due to this, one 
controller uses scsi id 6)

This seems to work ok. 

But if i play around sending RESERVE_UNIT (or RELEASE_UNIT) commands using 
SCSI_IOCTL_SEND_COMMAND i get scsi bus resets. (sometimes other errors too)

Code to do this is derived from scsiinfo-1.7.
I tried both the (bsd) ncr and the new symbios driver. Same results. 

Does anyone have a clue regarding this setup or experiences with 
reserve/release unit ?

-Michael
