Comment 27 for bug 708286

Seth,

I finally managed to update the BIOS on this machine to the most recent available as of today.

BIOS was upgraded from version 1.50 to version 2.10.
EC remained at version 1.40.

With this new BIOS behavior is still the same as in the original description.

I also tried all the kernel command line options you suggested, they all have the same behavior, except the last one (acpi_skip_timer_override). With that one, consistently, the system enters suspend, power light blinking, but when I press the power button, it behaves as if I'd just powered on the machine, i.e. suspend state and memory contents are lost and the system reboots afresh.

Let me know if there's something else we can try on this machine.

Waiting for cking's ideas to materialize sounds good, although I'm not sure the kernel is even there when the machine resumes (it looks to me like the kernel "dies" before putting things into suspension), so in this case some way of seeing what the kernel is doing while preparing to suspend could be more useful.

Thanks again for all your help!
