@Colin King First, I'm glad to see somebody from kernel team here ;-)
Second, I've tried your "pcie_aspm=off" kernel parameter. Short answer: ----------------- It DOES work for me. I will observe my machine and report, if it crashed. For now, I type this message on machine running on battery. Long answer: ----------------- I did undo the changes in /etc/pm/power.d from my post #50. Then I switched off the machine. Turned on, logged on, waited 1 minute, synced and pulled off the power cord. System crashed after 7-8 seconds. By doing this I verified, that the bug is still present. So far so good. Then I started machine again, logged in, done what post #76 wants, turned machine off. Turned machine on, logged in, waited 1 minute, synced, pulled power cord off the laptop and NOTHING bad has happened. Very good, Colin. I already expected ACPI BIOS of my Dell machine to be the suspect, but what makes no sense to me is that I have this freezing problem only with Intel 4965AGN WiFi card...
