Subject: Re: 2.6.19-rc1 lost ACPI events after suspend
after a little more playing around:
I unloaded all acpi-related modules (still without having rebooted)
# for a in ibm_acpi ac battery button dock fan i2c_ec processor thermal video container; do modprobe -r $a; done
FATAL: Module processor is in use.
than restarting acpid which triggers loading of all modules
I get this in the log:
