Can repeat behavior on Dell Studio with Intel integrated graphics:

1. System suspends successfully.
2. System powers on and disk starts spinning. However, no backlight on laptop screen, and host is unreachable by ssh/ping.
3. Hard power off (push/hold power button) then back on

I've attached full outputs of lshw, lsmod, lspci, lsb_release, uname -a, but the highlights:

- Intel integrated graphics, apparently with i915 driver.
- 2.6.32-21-generic, 64bit
- Lucid

Note: I also went through the both debugging guides at

https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume#Suspending
https://wiki.ubuntu.com/DebuggingKernelSuspend

With nothing fruitful. It's definitely suspending, but not resuming properly, no kernel panic, just not usable
