Suspend test fails for System Testing

[Walter_Wittel]

When running the "System Testing" suspend test (tried twice) from booted from Beta 2 USB stick the screen goes black but system doesn't suspend or return to desktop. Wireless LED continues to blink. Short press of power button doesn't return control, so long press / power off reset is needed. This hardware suspends fine from 11.10 desktop (booted from partition on HD).

I just tried syspend from the system menu and it works correctly (system was suspended and returns when a key is pressed). So maybe this is a problem with System Testing rather than the OS itself.
