Mario, you don't need to cc me on your messages. They just arrive in the same folder as traffic from the mailing list, due to my filter constructions.

Lost ticks indicates something seriously wrong at the system core -- it
could even be a marginal/off-frequency crystal oscillator. Here's my

1. cpu temp./stability: fans, heat sinks, overclocking via the BIOS?
2. memory quality & timing settings in BIOS?
x. power supply (done)

OK, now I don't have to suggest these :-)

But the arrival of your message was very timely -- it allowed me to think of wrong CPU core voltage. Devastating for the system, particularly if set too high. In addition to potentially damaging the CPU, too high a core voltage should also have the same effect as overclocking the CPU only, but leaving the rest of the system speeds unchanged. That should look like we are losing ticks.

Clark's message also makes me wonder if in the 2.6 kernels, tolerances have suddenly become very strict. I hope not, as this would suddenly shut out a great deal of the lower-end hardware, and with it a huge number of potential Linux users.

If these check out but the problem persists, I recommend a Timex
motherboard! :-) :-) :-) [sorry. couldn't resist]

Sacrificing the chicken has a better chance of working :-)
