------- Additional Comments From [EMAIL PROTECTED] 2006-05-06 14:31 ------- I have tried out the InstantOn dsdt on my Amilo M3438G (added it into initrd) and my laptop hung after I rebooted the system. With switching acpi support off I was able to boot again and changed the dsdt file with a file, I extracted from the bios of the machine and booting with acpi works again. I also recognized that PowerCinema Instant On does not have the fan problems. My question is how the dsdt from Power Cinema InstantOn was obtained? I have analyzed the PowerCinema system installed on Amilo M3438G for myself and found out, that its file initrd.gz does not contain a dsdt file. The supplied dsdt file only differs from the one in the bios in some lines (I have attached a diff file) but these lines cause the Amilo to hang while starting up. I am not really sure, whether the following notes will help to solve the problem, but perhaps they contain some interesting facts: 1. The acpid config directory of Power Cinema's Instant On only contain one entry for the power button. 2. Instant On comes with a lot of kernel modules for acpi like battery, thermal and fan whereas only battery is loaded in the startup script "run" that is contained in the file "image" that is in turn mounted as /dev/loop0 from the script "rclinux" that is contained in "initrd.gz" that is loaded by a modified grub (installed by ion_install.exe). 3. I was not able to find out why the program "run" and not "init" will be started by the kernel (a busybox init program is present, but no inittabs or a rc.d directory). So I have to assume that the kernel was also modified to boot "run" and not "init". 4. I have grepped all contained programs of Instant On (mostly python scripts) for calls to load acpi modules or call some of the appropriate scripts in scripts but could not find any occurences. The next consequent step would be to change the "run" script in order to get a shell and list the loaded modules but unfortunately, I do not have alot of time. 5. When I start my Amilo with SuSE 10.0, the fan stays silent for about thirty seconds and then increases to full speed. The delay is always the same. Perhaps a kernel thread that ios not started by InstantOn is causing too much load so that the fan is always on? 6. The slow down button on the Amilo also works correctly under SuSE 10.0, even the blue light goes on. 7. I have told Power Cinema about the fan problem, but they only answered, that they only sell the codecs and the linux port was made by third party vendors. 8. Last thought: I do not know for 100 percent, if the noise is coming from the fan of the processor or the fan of the nvidia graphic card. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------- Using Tomcat but need to do more?
