[ltp] Hang at wakeup from suspend

[Phil Shotton]

I'm getting an unusual hang after waking up from suspend. The screen is 
locked, but the password dialogue doesn't come up. Mouse pointer is 
still moving. I can kill the X server, it restarts and I then get the 
login screen. I can type my name, but it doesn't get as far as password 
entry. If I go to a vt I get the same thing. Login prompt accepts user 
name and then hangs before prompting for password. Eventually everything 
locks solid, and the way out is a reboot.

Sometimes I can't even type login name, but I can still switch between vts.

I'm running hardy heron on a T60p with ATI Mobility FireGL V5250. I'm 
running the latest radeon driver built from xf86-video-ati git about a 
week ago, but otherwise everything is stock.
There's nothing obvious in /var/log/messages. I used to get this 
occasionally with gutsy, but hardy seems worse.

Any suggestions as to where I go to diagnose and (hopefully) fix this - 
it's starting to get annoying!

Thanks
Phil
