The following reply was made to PR bin/1927; it has been noted by GNATS.

If not, you may load an lkm that performs an >"rtcin(RTC_INTR)" call to restart the RTC interrupt. This shows up rather dramatically on "systat -vmstat". It loudly yells "The alternate system clock has died!" and switches elsewhere. Hmm, It's interesting that systat has got special case code to detect this.... Is it really that expensive to do a simple watchdog for this event? > - Tor Egge Cheers, -Peter
