/*
 *      At IRQ rates >= 4096Hz, an interrupt may get lost altogether.    
 *      (usually during an IDE disk interrupt, with IRQ unmasking off)   
 *      Since the interrupt handler doesn't get called, the IRQ status   
 *      byte doesn't get read, and the RTC stops generating interrupts.  
 *      A timer is set, and will call this function if/when that
happens.
 *      To get it out of this stalled state, we just read the status.
 *      At least a jiffy of interrupts (rtc_freq/HZ) will have been
lost.
 *      (You *really* shouldn't be trying to use a non-realtime system
 *      for something that requires a steady > 1KHz signal anyways.)

void rtc_dropped_irq(unsigned long data)
{
        unsigned long flags;

        printk(KERN_INFO "rtc: lost some interrupts at %ldHz.\n",
rtc_freq);
...

atd atd. navrhuji minutu ticha za umrely hardware a transport do
servisu. videl bych to na board.
