> Gets odder! Ok, Nearing completion of this tale I think.. Turns out there is a known problem with psmouse, which leaves the system / ACPI / something in a bad state if psmouse is loaded before shutdown or reboot. Googling tells me that either removing batteries, AC etc.. before powering up, booting Windows, or shutting down Linux with psmouse removed, will "fix" the symptoms. Magic... Removing psmouse before boot from the init scripts, I reboot (no ec_intr=0), and not only does the battery status work properly, the CPU frequency scaling also works up to the CPU's maximum 2Ghz (which it never did before, it only ever reached 1.6Ghz). I'm now inclined to wonder if the F.08 BIOS might have worked ok, and provided the appropriate SSDT for CPU speed control, had the psmouse module been removed before reboot. Unless anyone is keen to know the results, I'm not that motivated to find out (by upgrading the bios again), as I'm not keen to either wear out the bios flash chip, or have a random corruption during an update. Thanks for all the help so far, Regards Peter Clifton. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
