Update of /a/cvsroot/src/sys/arch/sparc/dev
In directory pain.lcs.mit.edu:/b/tmp/cvs-serv647

Modified Files:
	xd.c 
Log Message:
- moved disk_busy() call from xdstrategy() to xdc_startbuf()
	[prevents disk_unbusy panic when disk is loaded (if no
	free IOPBs, xdstrategy() would queue the buffer for pickup
	by xdcintr() but xdcintr() would never call disk_busy().
	xdc_startbuf() is a better place since all bufs are routed
	through here]   problem detected by girish@dworkin.wustl.edu,
	diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
	XDC_FREE() [don't want to access a data structure that was just put
	on a free list]
