Re: Invalid PBLK length

I have installed the acpi-20021212 Patch on my Asus L2400D Laptop with a 2.4.20 Kernel (AMD Athlon XP mobile, SiS chipset, latest Bios version from Asus). First the good things: - I can monitor battery and temperature status - I get acpi events with acpid (powerbutton, ac_adapter) - I can send the laptop sleeping with echo 1 > /proc/acpi/sleep, but the processor does not really awake after pressing a key; the performance is quit sluggish bad things: - no processor throttling - only CPU state C1 I think this is caused by the Invalid PBLK length (Invalid PBLK length [5]) reported in /var/log/dmesg. I think this issue was discussed in this list before, but I did not see any conclusions/solutions.
Short term dirty hack: http://sourceforge.net/mailarchive/message.php?msg_id=2138093 Long term solution: Add a feature to ACPI (like CONFIG_ACPI_BROKEN_AML) which will make the kernel complain about a buggy BIOS but at the same time offer some workarounds. This goes towards bug to bug compatibility with M$. I think this is planned already, but development for this hasn't started yet.
Therefore the CPU is always in the most power consuming mode and the fan runs the most time as the temperature is above 70°C. However, I installed then athcool from http://members.jcom.home.ne.jp/jacobi/linux/softwares.html to disconnect the Northbridge when STPGNT is detected. To my surprise it worked.
I'm really surprised, too. I have the little brother of your notebook (the L2000D, see my page http://mitglied.lycos.de/chamo3/md9688.html), and tried something similar called VCool which didn't work. :-/
How can I get rid of this Invalid PBLK message and how can I use the sleep mode?
I have no idea why S1 doesn't work for you - I have the same hardware and it always worked (with every version of ACPI). Maybe it's a question of video driver or kernel setup? We can check these non-acpi issues in private mail if you want to.
