Hello fellows, I hope, I am right here with my problem. I'm using Debian unstable i386 on my dual Celeron 533 with a Abit BP6 Board and I am quite new to smp. I have here these really annoying APIC error on CPUn: 0n(0n) broadcasting over my consoles. As a matter of fact it's not only annoying me. When there is high cpu load (mostly when Seti@home is running) there seems to be a random freeze. After consulting google I made following steps to stop both, freezing and those error messages: + reduced cpu voltage from 2.0V to 1.95V with no effect + shutdown XFree with the effect, that Seti just causes apic errors and a another error message: ide_dmaproc : chipset supported ide_dma_lostirq func only : 13 hdb : lost interrupt but no freezing + disabled APM both in BIOS and in kernel with the effect that gkrellm doesn't shows correct cpu load (not more than 15% on cpu1 and 0% on cpu 2 while seti is running, not at all...) Also no apic errors occured in 30 minutes. As I switched from X to console a real flood of apic errors came over me. + disabled High-Point onboard IDE controller (which was in any case unused) So far from me and my "counter measures". Anybody out here who can help? I heard of a patch that eliminates the error messages, but doesn't fix the problem. I really could life with those errors, but not at all with a random freezing system.
