REPOST: RTC problems in Debian on Dell PowerEdge servers

I’ve had some problems with RTC on Dell PowerEdge servers with Debian 4.0 (etch), which were unfixable by all of the following: Set Hz to 100/250/1000 Try newer kernel Add –directisa option to hwclock (Would only fix a symptom of the problem, and not touch the problem itself at all) The symptoms: You get a lot of messages like this: rtc: lost some interrupts at 2048Hz This varies (in my case) between 1024Hz, 2048Hz and 4096Hz....
