As a result, the system is now able to return from hibernation and is functioning almost normally, except that ACPI stops working. Neither "tail -f /var/log/acpid", nor "sudo strace -p `pidof acpid`" report *anything* when I, for example, plug or unplug the power cord. So, I figure ACPI is broken after return from hibernation.
I tried to set the magic option to nvidia kernel module as per the following URL:

The option is:
options nvidia NVreg_SoftEDIDs=0

Any ideas how to fight this?
