Bug Description
Suspend to ram results in a frozen machine on resume. Hibernate is not even being attempted at this time. System specs are a Lenovo Thinkpad T500 with an intel X4500HD. No ATI card. lspci attached. There is no interesting kernel log after suspend. I suspect it doesn't get to the point where it can write a log to the hard drive.
***Workaround for those with this issue***
Install the linux-image-rt package and related rt packages
edit your /boot/grub/
Copy /usr/lib/
make your suspend modules read: SUSPEND_
Rejoice!

I second this. The system goes to sleep fine but does not resume properly. In my case it is blank screen and not even the magic SysRq keys work.
The following seems to work sometimes when run from a tty:
pm-suspend --quirk-vbe-post --quirk- vbestate- restore --quirk-dpms-on
