[ltp] Crash on resume

[Richard Neill]

Thanks for that. I'm not entirely sure what this means, (I'm still a 
newbie at heart!) - can you explain a bit more why it might be the cause 
of a rather random error? I've never had data corruption as far as I know.

If it's relevant, I had an X-freeze yesterday while playing Tuxracer. So 
I at least partly suspect XF86. When X freezes, of course the mouse and 
keyboard don't respond. Without another machine to ssh in, all I can do 
is Alt-Sysrq-S,U,B. The sysrq key does usually still work. An idea - is 
it possible to modify the sysrq code to add the function "kill X, dump 
me at a console"?
