Nothing > special. I guess some SMM interrupt is reading the the PCI regs and sends it to EC. I blacklisted the k8temp driver (and the out-of-tree k8_edac driver in Fedora) and the temps were still volatile, so that's not causing it. Since then I've upgraded the system BIOS from F.06 to F.27 and the problems _may_ have gone away. My own custom 2.6.19 kernel has never been a problem, so I'm thinking it's one of these drivers loaded by Fedora that I never even compile: i2c_core i2c_ec i2c_piix4 asus_acpi (on a Compaq???) sbs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
