Does suspend2 change the behavior of the system for suspend to mem, or is it only for suspend to disk? I hesitated to use these patches, as the debian kernel is far from a vanilla kernel, and I don't think they packaged a version of it. > You'll probably want to poke around /proc/acpi and such to find out if > C1, C2, and C3 are getting entered a reasonable amount of time by the > processor.

The system actually goes in sleep mode, I don't know which part of the hardware does not. By comparing the list of PCI devices being disabled (in the log I sent in the previous message) with the output of lspci, it seems that the graphical card is not disabled. But I don't know if some other part of the code does the job, neither do I know what this 'disabled' state actually means (maybe only regarding interrupts?) > Last thing I can think of, try building a kernel that uses APM (it's > still available under Power Management as far as I recall) instead of > ACPI and see how it works for comparison purposes. I was hoping I could start using debian's packaged kernels again :-) In fact, APM worked well in 2.6.8, but from that version upward, it really was a source of random crashes when the system was going up again. I was not using then hibernate script at that time. Do you think it would have improved the experience?
