Of course, and too bad, not everything is supported in terms of acpi and I am eager to look into this problem. I will enumerate on my issues and observations here, hoping some willing ear would lend a helping hand. I am running ubuntu edgy beta now which runs the 2.6.17-10 kernel and I have seen the same issues in ubuntu dapper which has a 2.6.15 kernel. 1. When booting the machine in a default configuration, it hangs (kernel does not respond to any sysrq key combinations) after the following lines: using HPET for base-timer using HPET for gettimeofday Detected 2000.186 MHz processor Using hpet for high-res timesource. Playing with some kernel parameters, I notice the following behaviour: no effects with pci=noacpi, acpi=force,noapic, nohpet, ... What does work is: acpi=off but then I have no acpi at all, another option I discovered is hpet=disable, which enables some of the acpi functionalities. 2. with the hpet=disable parameter, I can see battery state, but remainng time is calculated incorrectly (always giving the same amount of minutes), plugging in and out the adapter is recognized however. Reading temperature does not work as he always gives the constant heat of 75 degrees. Cpu frequency scaling does not work. 3. output of dmesg | grep ACPI and dmesg are in attachment. 4. While booting the kernel, but apparently before putting things in the kernel log, some messages appear (three), among which something about a BIOS bug. They flash away too fast for me to write them down, so a way of capturing these is appreciated. 5. Would fixing the DSDT (of which I read some stuff here and there) be helpful in my case? Is it dangerous? Is there someone to walk me through it? 6. My BIOS is v1.01 and is definitely the current version as it is a very new laptop in general. Any help is greatly appreciated!
