[ltp] Crash on resume

[Richard Neill]

Dear All,

I wonder if anyone can help with this. I'm using an A22p, with Mandrake 
8.2 I have it set to suspend (to RAM, not hibernate) after about 45 
minutes. (The Xscreensaver package usually kicks in first after 20 min).

However, one time in 5 (or so), the machine won't wake from suspend. I 
press the "Fn" key, and the cdrom "gronks", the display comes back on, 
showing a distorted image of what was there before suspend, and it then 
freezes. The HDD doesn't spin up, and the keyboard is not responsive 
(except for some bios things like Fn-PgUp for the thinklight and screen 
brightness etc). I have to kill it with the power switch.

This used to happen about once a month, but it now seems much more 
frequent - every few days (and of course, this is when I most need 
stablility to write my thesis!) Any ideas what's happening?

1)What might be causing the problem? I have a few ideas - maybe these 
are all spurious:

	- 1) The HDD has a fault - something causes it not to spin back
		up

	- 2) It's not really a linux crash, but a hard-lock-up of X ?
	(I'm using XF86-4.20)

	- 3) Modem Driver (Lucent)

	-4) Some application is trying to use the network which it can't
	 access. (Mozilla?) [I have had the problem whether I use no
	network, dhcp network or 'regular' network]

	-5) Xscreensaver package - some of the screensavers (OpenGL
	 ones??) which normally work fine may crash on suspend/resume?

	-6) IBM BIOS is at fault

2)Is there anything I can do to log where it goes wrong? It's an 
intermittent fault - I can't reproduce it at will

Thanks for your help

Richard
