CVS commit: src/sys/dev/acpi/acpica

[Jukka Ruohonen <jruoho%netbsd.org@localhost>]

Module Name:    src
Committed By:   jruoho
Date:           Wed May 12 17:03:11 UTC 2010

Modified Files:
        src/sys/dev/acpi/acpica: OsdSchedule.c

Log Message:
Print a warning if AcpiOsSleep() is called with a value larger than two
seconds. It is known that there are systems in the field that pass bogus AML
values to the Sleep() operation code, possibly requesting delays that could
be measured in days.

Discussed with jmcneill@.

XXX: While the used mstohz(9) is documented to round to one second if the
     passed value is larger than 131072 ms, we may still need to force a
     sensible upper limit if this warning starts to appear.
