kernel/3373: Thinkpad R31 APM Kernel Problem

>Number: 3373
net
>Environment:

	Machine is an IBM Thinkpad R31
	OS is OpenBSD Current
	System      : OpenBSD 3.3
	Architecture: OpenBSD.i386
	Machine     : i386

>Description:

	When shutting the lid of the laptop or making the following apm calls :                                                                           
	apm -S : causes the laptop to go into standby and then immediately come out
	of it to the HDD power up password, where it freezes                                                     
	(not responding to pings or connections, and no keyboard response)                                   
											
	apm -z : causes the laptop to go into suspend and then immediately come out
	of it to the HDD power up password, password is accepted and screen returns                        
	to previous state, however mouse and keyboard do not respond, and machine
	is frozen
	(not responding to pings or connections, and no keyboard response)       
	
	These symptoms occur in exactly the same way, both from within X, and from a terminal.

	Also using Fn-F4 cause the machine to crash to a terminal with no response, and a black screen,
	+again no ping response or connections.

	The dmesg during boot time is as follows :

	I have upgraded the laptops firmware to the latest version, no change in problem.

	I have tried disabling the "machdep.apmhalt=1" line in sysctl.conf file, also without success.
	
	I have tried using a recompiled kernel with the line "option APM_DISABLE_INTERRUPTS=0" included.
	No success either. NB : The problem occurs under the GENERIC kernel which I normally use.

	I have also tried turning off PCI related power options in the BIOS settings, and have also disabled all
	BIOS passwords.  Still no luck.

>How-To-Repeat:

	Any of the following actions will trigger the problem :
		- call apm with either -S or -z options
		- shut lid of laptop (triggers suspend)
		- using key sequence Fn-F4

>Fix:

	None that I am aware of.
