>Originator:     Wilko Bulte
>Release:        FreeBSD -current as of 7/23/2001
>Organization:
Private FreeBSD site - The Netherlands
>Environment:

        -current as of Jul 23, 2001. PTI isp2100 based FC HBA.
	Any x86 or axp box.

>Description:

        Powering down FC disk cab results in LIP, noted by the isp driver.
	This is OK. Running for example camcontrol rescan on the FC
	loop/bus results in camcontrol hanging in 'cbwait' forever.
	The I/O request obviously never times out.

>How-To-Repeat:

	See description

>Fix:

	Some timeout mechanism needs to be implemented so that a dead FCAL
	can be detected and attached FC/SCSI devices can be declared 'gone'
	properly.
