Suspend doesn't always resume

[Alex]

Hi,

I have a fedora15 x86_64 install on an AMD Phenom system and doesn't
always resume from suspend. I have no idea how to troubleshoot this or
any idea why this would be happening. What can be done to fix this?

When pressing the power button to resume, the computer powers on but
is unresponsive. No display, USB mouse doesn't illuminate, can't
access it remotely. It's just lights on, no one home.

I've included a few details about my system below.

Is there something that specifically I should investigate with the
BIOS configuration?

Is there a more specific forum that would be better suited for ideas here?
Any ideas greatly appreciated.

Thanks,
Alex
