Comment 3 for bug 204588

Same issue here on an HP/Compaq 6720s - Celeron M540 processor running Hardy 64-bit.

Suspend seems to go fine, but the machine won't resume. The power light comes on correctly but the machine freezes with a blank screen, backlight off, the caps lock light won't toggle when caps-lock is pressed, and the machine won't respond to network pings. I have to hold down the power button for several seconds to turn the machine off.

The selfsame machine running Gutsy suspends and resumes correctly except that the backlight occasionally doesn't come back on, and I have to use the brightness function keys to bring it back.
