On this system, with the 2.6.38-3.30 kernel as installed by default with the Natty image from 20110214, upon attempting to resume after suspend, the system is unresponsive (black screen, no keyboard response, no network/ping from other systems). Poweroff is the only option available.
I tried the other, older available kernel (2.6.38-2.29), with this kernel suspend works fine and without issues.
Steps to reproduce:
1- Install Natty (20110214) on the HP ProBook 6550b
2- Upon bootup, select "suspend" from the panel
3- Wait until power light is blinking indicating suspend mode, then press power button
Expected result:
- System resumes correctly and continues working
Actual result:
- As indicated above

Tested mainline kernel http://
With that kernel, the system also fails to recover from suspend.
