Description grandi 2003-04-09 03:10:01 UTC 
	LINT in STABLE provides a procedure to "wire down" SCSI devices so a
given bus, target and LUN always has the same device name.  A very useful
tool.  Unfortunately, the procedure in LINT doesn't work!

Given the config file below, the results of "make buildkernel" is:

archive# cd /usr/src
archive# make buildkernel

--------------------------------------------------------------

Fix: The most obvious fix is to excise that portion of LINT; but it sure
would be nice if there was a working procedure in STABLE to wire down SCSI
devices.
How-To-Repeat: 	try to build a kernel with the procedure in LINT

Thanks to Scott Long and Wilko Bulte who both supplied the trick to get
this working.  Following is a context diff for LINT to properly describe
reality.

+ # NOTE: for this example syntax to work, the device entry for ahc must
+ # be changed to device entres for ahc0, ahc1 and ahc2.  In other words
+ # instead of:
+
+ #device		ahc		# AHA2940 and onboard AIC7xxx devices
+
+ # use the following:
+
+ #device		ahc0		# AHA2940 and onboard AIC7xxx devices
+ #device		ahc1		# AHA2940 and onboard AIC7xxx devices
+ #device		ahc2		# AHA2940 and onboard AIC7xxx devices
+
  # "units" (SCSI logical unit number) that are not specified are
  # treated as if specified as LUN 0.
