Use FWTS (firmware test suite) for ACPI Component Architecture diagnosis

My purpose for this snippet is to review the FWTS for diagnosing the ACPI error log during systemd bootup. ACPI is a complex system, what i had given here is really entry level to explore the firmware test suite on Ubuntu 16.04 LTS on my Lenovo T400 laptop. Hopefully you can venture even further than i do. Ahoy!

less /sys/module/acpi/parameters/aml_debug_output

if '0' then debug output is off. We can write '1' as a parameter to enable debug output

less /sys/module/acpi/parameters/acpica_version

The output shows the acpica version in use by the OS.

sudo fwts oops acpiinfo fadt madt rsdp -f -r apic.log -D | dialog --gauge "FWTS" 10 90

This runs the 'acpiinfo' 'fadt' 'madt' 'rsdp' test of the fwts suite. The "dialog" command allows you to visually see the processing of the "fwts" command

The acpidump command allows you to get the dump the debug output of acpi for analysis using "acpixtract" command as shown in the following.

sudo acpidump -o acpi_dump

acpixtract -l acpi_dump.dat

 There is more to explore as can be seen from the information in manpages of acpidump and acpixtract. I shall leave you to do it and hopefully debug the error

A "apic.log" report is generated for you to analyse the error appearing in the booting up of the Linux kernel based OS.

Repairing Fedora Grub using Fedora Live USB

First, Prepare the Fedora Workstation Live CD using Fedora Media Writer. Next, run the Workstation Live CD and run the console. Then, enter the following commands if you are running the separate boot and root partition: 1) sudo mount /dev/sdaX /mnt Note: sdaX is the root partition 2) sudo mount /dev/sdaW /mnt/boot Note: sdaW is the boot partition The following files are essential for running the essential processes for repairing grub and shall be mounted: 3) sudo mount --bind /dev /mnt/dev 4) sudo mount --bind /proc /mnt/proc 5) sudo mount --bind /sys /mnt/sys 6) sudo mount --bind /var/run /mnt/var/run Now, you are ready to go into the Fedora partitions to repair the grub files. The path should be changed to root user from liveuser> to root>: 7) sudo chroot /mnt If you are running dual boot Windows and Fedora system, the following command will replace the Metro Interface: 8) grub2-install /dev/sda With a dual-boot or multi-boot systems, the follow

Installing SUSE Imagewriter on Linux Mint Debian Edition

The original title for this post is "Installing SUSE Imagewriter on Ubuntu LTS". Download Zip, save to preferred directory:~/Downloads However due to data loss of the blog, i decide to rewrite this article using Linux Mint Debian Editi on ( a similar distribution to Ubuntu ). First we have to download the source from Github (https://github.com/openSUSE/imagewriter) Download ZIP, save to preferred directory: ~/Downloads Extract imagewriter-master.zip in /home/username/Downloads and in terminal run the command: cd /home/username/Downloads/imagewriter-master Install the latest version of qt4-qmake and libqt4-dev by running: sudo apt-get update && sudo apt-get install qt4-qmake libqt4-dev Instructions for Linux Installation on github Follow the instructions in README.md by running the command: qmake DEFINES=USEHAL imagewriter.pro  Follow by the command: qmake DEFINES=USEUDISKS imagewriter.pro Next run the command: qmake DEFINE

Fixing time on sysvinit and systemd

If you have a system that boot using different GNU/Linux init systems such as sysvinit (aka System 5) and systemd (aka System 500) in addition to proprietary Windows system, you may face incorrect time display on one of the aforementioned system. The difference in time display is dependent on the time difference of your location and the UTC time. Further complication may result from concept like Daylight Saving Time (DST). If the Bios is set to localtime, you may fix it in systemd boot system using 'timedatectl' command like: sudo timedatectl set-local-rtc 1 However, if you are using sysvinit and Bios is using localtime, you can set inform the system that local time is being used using 'hwclock' command like: sudo hwclock --localtime or to synchronize the hardware clock with system time and inform the system using: sudo hwclock --systohc --localtime If Bios is using UTC time, you may revert the change with 'timedatectl' like: sudo timedatectl set-lo
