thinkpad T400 laptop crashes when going to sleep

[Tim Lunn]

Binary package hint: upower

Since upgrading to maverick, my laptop will completely crash out when going to sleep sometimes. Probably happens 1 in 3 times I try to sleep

After closing the lid (which is set to suspend), the led sleep indicator just flashes continuously. suggesting that there has been an error, and not actually made it into sleep. normally laptop will beep and the led stays on (not flashing)

When I open up again, screen remains blank, cant login, cant change to VT terminal and cant login over network with ssh.

Not really sure how to track down any error messages, so please let me know which logs I can attach for futher information.
