           Summary: Make Realtime clock wakeup alarm available
           Product: openSUSE 10.3
           Version: Alpha 1
          Platform: i586
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: Kernel
        AssignedTo: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx
        ReportedBy: tschmidt@xxxxxxxxxx

Please unset CONFIG_RTC and CONFIG_GEN_RTC in the default kernel configuration, 
so that /sys/class/rtc/rtc0/* is available, as it was removed from /proc/acpi
with 2.6.22.

I found another problem with this interface: 
echo 1182948552 > /sys/class/rtc/rtc0/wakealarm; cat
/sys/class/rtc/rtc0/wakealarm 
returns 2051637448 

Maybe a problem with BIOS not saving the century? (see also
http://lkml.org/lkml/2007/6/19/264
Also it seems, that /sys/class/rtc/rtc0/wakealarm only accepts times more than
2h in the future. 
With the old interface /proc/acpi/alarm it was working fine. (Machine is:
