ACPI Error: Could not enable RealTimeClock event (20140214/evxfevnt-212)

ACPI Error: Could not enable RealTimeClock event (20140214/evxfevnt-212)

[Borislav Petkov]

Hi guys,

so I get this with rc7+tip but not with rc6+tip:

ACPI Error: Could not enable RealTimeClock event (20140214/evxfevnt-212)
ACPI Warning: Could not enable fixed event - RealTimeClock (4) (20140214/evxface-628)

rtc_cmos gets initialized fine with both though:

rc6+tip:
========
rtc_cmos 00:06: RTC can wake from S4
rtc_cmos 00:06: rtc core: registered rtc_cmos as rtc0
rtc_cmos 00:06: alarms up to one year, y3k, 242 bytes nvram, hpet irqs
rtc_cmos 00:06: setting system clock to 2014-05-26 17:21:31 UTC (1401124891)


rc7+tip:
========
rtc_cmos 00:06: RTC can wake from S4
rtc_cmos 00:06: rtc core: registered rtc_cmos as rtc0
rtc_cmos 00:06: alarms up to one year, y3k, 242 bytes nvram, hpet irqs
rtc_cmos 00:06: setting system clock to 2014-05-26 17:50:18 UTC (1401126618)

Any ideas?

Thanks.

Does it happen on -rc7 w/o tip?

Looking at the -rc6 to -rc7 commit list, I don't see anything that
pops out at me.  There's no changes to drivers/rtc nor drivers/acpi.

The only change that might be relevant from arch/x86/ is:
a4b4f11b2783ec678cccb4ce7e4ce9665aa04a24 (perf/x86/intel: Fix
Silvermont's event constraints).  Any other hardware details, etc?

thanks

Yeah, I just did a fresh merge of Linus' master + tip/master and the
error message is gone. It could've been a glitch so I'll watch out for
it if it reappears.

Thanks.
