same for me. HD light on solid, and totally unresponsive. With an HP
zv5000 amd64 laptop.

Funny, I was just looking at similar bugs. There's a patch linked here:
http://bugzilla.kernel.org/show_bug.cgi?id=2039

It's supposed to call the acpi suspend methods for IDE, which linux
apparently doesn't do. The newer version still applies to 2.6.17.

It didn't help me though. Maybe one of the irq-setup boot options would
fix it? I've messed around with 'pci=noacpi' and 'pci=routeirq', but
same problem. Also, this system gripes about needing 'pci=assign-busses'
but I haven't looked into that. Using it or not makes no difference.

I'm kind of stuck too. I don't know how you debug a problem that causes
your hard drive to lock up while video's still disabled during resume.

I have serial on this laptop, maybe that would work. Haven't tried.

I only have one clue, and it's weird. I use grub with "default saved"
and "savedefault", so whatever kernel was booted last is always the
default. I boot into entry 0, attempt suspend-to-ram, and get the
frozen-system/no-video/hard-drive-light-on resume lockup. I hold down
the power button for a few seconds to power it off. When I turn the
system on again, the 2nd entry in the grub menu is now the default!

I'm not using grub's "fallback" or "savedefault" with an argument. And
anyway, I'm resuming from ram, so grub shouldn't be run at all. And even
if grub did run, it would not change the default entry without user
interaction.

weird.
