Re: [Pi 3525] 64bit OS problems - random reboots with 4 GB RAM!

P.S. how's everybody doing, 1.10c flashed already and running x64/4GB without any issues? 8) I've noticed that my webcam always goes on after shutdown with new BIOS 1.10c. With previous versions the cam was able to 'remember' the power state - on or off. It's not that a big deal is :P Like the swit...

Re: [Pi 3525] 64bit OS problems - random reboots with 4 GB RAM!

As NeoLojik says, the BIOS upgrade is a delicate operation, so do it at your own risk. Although the CD I uploaded is the one I've used this morning without problems. I forgot to mention that when you boot with the CD, you must write the following command and press <ENTER>: phlash16 /c /cs /s /x flas...

Re: [Pi 3525] 64bit OS problems - random reboots with 4 GB RAM!

What good news!
I've made a boot cd to upgrade the bios. You can download the ISO from here: http://www.2shared.com/file/11217364/85 ... ootcd.html

Re: [Pi 3525] 64bit OS problems - constant restarting!

Merry Christmas and thank you all (oversized and neolojik) for your efforts and time trying to workaround this problem.
During these days, I'll run an Ubuntu 9.10 live-cd to verify its stability in this notebook.

Re: [Pi 3525] 64bit OS problems - constant restarting!

Hi NeoLojik, last night I have patched the DSDT table like you. My Pi3525 has Ubuntu 9.04 x86_64 installed and I can check that It loads the custom DSDT inspecting the dmsg output: [ 0.004226] ACPI: Checking initramfs for custom DSDT [ 0.305037] ACPI: Found DSDT in DSDT.aml. I can't see those lines ...

Re: [Pi 3525] 64bit OS problems - constant restarting!

I have opened another line of research related to the ACPI tables. See how to fix commons ACPI problems (http://forums.gentoo.org/viewtopic.php?t=122145). I have dissasembled and recompiled DSDT with the following results: ercilla@ercilla-laptop:~/tmp/acpi$ iasl -tc dsdt.dsl Intel ACPI Component Arc...

Re: [Pi 3525] 64bit OS problems - constant restarting!

After many tests I give up. Anyway, I comment here on the tests I've done so anyone waste the time with the same tests. In NeoLojik tests, the modules "thermal" and "processor" were those that caused the machine to reboot. In the ACPI specification said that "When the therma...

Re: [Pi 3525] 64bit OS problems - constant restarting!

Well, that is a big step certainly ! :) Are you sure it's that stable? I managed that too couple of times with different 64bit systems, but... after some 2-3 hours of normal work the thing goes for a reboot again :evil: Today I'll leave running all day with these settings and will discuss here the ...

Re: [Pi 3525] 64bit OS problems - constant restarting!

One note: with 64 bits, detecting the 4G and over 2 hours stressing the machine with cpu and memory intensive processes and still not restart... replace "mem=4096m" by "iommu=noaperture, allowed, memaper, soft"

I'm going to bed, tomorrow more tests...

Re: [Pi 3525] 64bit OS problems - constant restarting!

Oversized, I have no experience with OpenSolaris, but my guess is that your instalation of OpenSolaris 32 bits has PAE enabled (perhaps the installer detects that you have 4Gb and install the kernel with PAE). NeoLojik, thank you very much for the clear explanations. Just out of curiosity, could you...

Re: [Pi 3525] 64bit OS problems - constant restarting!

Hi oversized, a few months ago I decided to install xubuntu 64 bit instead of 32 bits + pae thinking that fujitsu will release a patch for the BIOS. Now it would be very costly to reinstall everything (I use the laptop to work and I have a lot of software installed and configured). Furthermore, it a...

Re: [Pi 3525] 64bit OS problems - constant restarting!

Hi, the last summer I bought the Amilo Pi 3525 with 4Gb of memory and its problems of random reboots with 64 bits OS. I found this forum and finally decided to install Xubuntu 64bits booting with mem=4096m (hereinafter "the hack") that paradoxically makes for less than 4GB available, with ...
