"rtc: lost some interrupts at 1024Hz." Messages Again

I got a lot of "rtc: lost some interrupts at 1024Hz." messages after installed zaptel-1.4.11 and the ztdummy module was enabled.

The PC platform details:
- Debian GNU/Linux 4.0r1 on i386 with update applied
- Shuttle KPC K45 Barebones
- CPU Celeron C430 1.8 GHz

I can fix this problem by applying the method in my previous post on 6-Oct-2007. However, when I press the power button, the system power off immediately instead of a clean shutdown. After a lot tries, I still cannot fix the power button problem.

Finally, I reinstall the system using Debian GNU/Linux 4.0r3 on Amd64 (i.e. 64-bit version). The "rtc: lost some interrupts at 1024Hz." never occur again.
