At the very least, year will be set to -1. This then gets passed through to rtc_tm_to_time, which results in reading wakealarm providing very odd feedback. I guess the "right" fix is for rtc_tm_to_time to use the current values for anything that's -1? > + rtc_control = CMOS_READ(RTC_CONTROL); > + rtc_control &= ~(RTC_PIE | RTC_AIE | RTC_UIE); Do you really want to clobber RTC_AIE on probe? If an alarm has been set by the BIOS, it seems a little unfair to disable it on boot. -- Matthew Garrett | mjg59@srcf.ucam.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
