>Description:
	Well, unfortunately I can't be terribly precise, since I was just using
	the system and suddenly all disk access appeared to hang and the console
	is now repeating:

	sd0(ahc0:0:0:0): adapter resource shortage

	and

	sd1(ahc0:0:1:0): adapter resource shortage

	I can provide the full kernel config if that would be of use to
	anyone.  The adapter is an Adaptec 2940UW, and it is being driven by
	the ahc driver.  I have `options AHC_TAGENABLE' if that makes any
	difference.

	I haven't seen this before on this machine, and I've had the box for
	about a year, but I've just upgraded to -current after quite a while
	of being at 1.5_ALPHA.

	I also installed 1.5GB RAM where it only had 128MB before.
>How-To-Repeat:
	This I am not sure, I wasn't really doing anything special I don't
	think.
