Thanks for the swift reply! If I choose processors, I get (among other normal things) this:What happens if you choose "core"?
Both core and processors always exhibit the same ACPI errors.

I do not get these ACPI Error and ACPI Exceptions in a normal run. Is this normal?No, it is not.quoted
Does it indicate a problem?A small one. It indicates that P-states as defined in the BIOS aren't usable to the ACPI cpufreq driver. There also seems to be a problem with the handling of the embedded controller, which may be more serious.
Should I report this to the ACPI list?

The dmesg of the pm-suspend after i have # echo "processors" > /sys/power/pm_test can be found here: https://dl.dropbox.com/u/63420/processors.txt The dmesg of a full pm-suspend run is here https://dl.dropbox.com/u/63420/full.txtThat seems to be a clean suspend/resume cycle. What's the problem, then?
Yes, I'm sorry if it wasn't clear. Since that was a fresh reboot, the suspend went OK. I posted it because I thought that these ACPI errors were directly relevant to the problem I'm having. But I am keeping track of all this info to have when this problem happens again but since my computer hard locked (this hasn't happened before!) when I opened the lid just 5 mins ago, and this happens about at 24 hours of uptime, I will probably have all the info collected by tomorrow. Sorry for the misunderstanding and thanks for the interest!
