It really > isn't. The BIOS bug in these machines is that they set the thermal trip points to 16 degrees C if the APIC is set up in a specific way. It's specific to the HPs and it was there in the initial BIOS release - before anyone added workarounds for the SB700 issue. It's clearly and unambiguously broken, and it's clearly the BIOS's fault. However, it's also clearly our responsibility to avoid triggering it on this hardware. -- Matthew Garrett | mjg59@...f.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
