I have a Hewlett-Packard HP EliteBook 840 G1 amd64 machine exhibiting strange bouts of acpi0 interrupt storms. Depending on some undetermined factor after a reboot the machine may come up with acpi0 interrupts firing 5k times per second. This boggles the machine down. There's a sure fire way to avoid the problem by disabling acpi in UKC. Naturally this makes the machine unable to sleep. I tried to collect some obvious things, but happy to produce more upon request.
