I've been spending a few days trying to get suspend-to-ram to work on my new HP NX7010 laptop. Haven't had much success though so I thought I might get some help from the more experienced. I'm running FC2 with linux 2.6.6. S3 has been tested using vanilla kernel and with the patch from acpi.sf.net. I've also included a patch from the ACPI bugzilla to be able to control which devices can wake the unit. The behaviour has been the same for all tests. I don't think the unit actually gets all the way into S3 though. If I turn on ACPI debug in the kernel I can see a debug message that says 'Entering S3' but the laptop doesn't power down anything. After this point the only way to get control of the machine again is to hold down the power button for a couple of seconds, bypassing the OS. Also, for some strange reason I have to do this twice because the machine hangs during POST after the first reset (after a failed suspend-to-ram that is, works fine otherwise). I've started looking in the ACPI spec. since I suspect the bug might be in the DSDT. I doesn't even compile cleanly with Intel's compiler as it is. ACPI is new to me however so I could use some pointers on where I should start looking. I'm also fluent in C so I intend to have a look at the kernel code and insert some debug statements. Might help me pinpoint where it hangs. I'd appreciate any help I can get. Just tell me what information you need and what I should test and I'll gladly do it. Suspend-to-ram is a badly needed function so I'm ready to devote whatever time is required to get this fixed.
