Suspend Fails to Resume
 

I have a Systemax Pursuit 2130 C27 BTO Notebook running Gentoo. I have the Gentoo kernel sources (not suspend2) and I have the hibernate script package installed.

When I 'hibernate -n' everything seems to work fine.

When I hibernate, it seems to work fine, too, and then appears to power down. I have to assume for now that it's keeping the ram powered; however, I'm not sure.

But when I press the power button to resume, the power comes back on (that is, the fan starts spinning) and the access lamps for the hard drive and the CD-ROM drive each flash twice (one at a time, going back and forth, not at the same time.) Then it just sits there.

Using the keyboard doesn't seem to do anything (can't get the caps lock to light or anything, machine doesn't reboot or anything), and I've let it sit for as long as a half hour, just to see if there was somthing going on that was really slow.

There is an ATI Radeon video chip, and I've tried using the vbetool to save and restore the state, as well as doing the hibernate in X (X.org 6.8.2), which had been suggested for ATI's. I've also tried doing it from the console with no framebuffer console and no X running. No dice.

Here's what 'lspci' prints out:

Here's my kernel command line:

/dev/hdc=ide-cd root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda5 acpi_sleep=s3_bios

I've tried doing it with acpi_sleep=s3_mode, as well as with no acpi_sleep option.

I've checked and tried the tricks and options suggested in other threads on suspend/resume.

Does anyone have any other ideas, or know what might be getting in the way of resuming?
