This script (triggered by a systemd service) collects ACPI information during boot and after waking up from hibernation.

Sometimes after waking up from hibernations I had some problems with the ACPI tables on my installation. To collect data hopefully useful in debugging this, this script was created.

There is a install.sh that copies acpi-data-collect to /usr/local/bin and installs a acpi-data-collect.service file. To actually enable that service you have to run:

systemctl enable acpi-data-collect.service

(optional): bootcounter, for better naming of collected data sets

The script collects this data:

• contents of /sys/firmware/acpi/tables (for this to succeed the script needs to be run as root)
• output of dmesg and dmidecode
• kern.log and syslog (compressed if they are >=1MB)

The script expects an output directory as first (and only) parameter and creates a new subdirectory for each run. If [bootcounter][bootcouter] is installed, the subdirectory will be called $BOOTNUMBER-$RUNNINGNUMBER. Without bootcounter, $BOOTNUMBER will always be 0.

For example:

$ acpi-data-collect datadir
$ ls -l datadir/0-1
total 24032
-rw-r--r-- 1 root staff    87171 Apr 19 13:56 dmesg
-rw-r--r-- 1 root staff    22702 Apr 19 13:56 dmidecode
-rw-r----- 1 root staff 24395994 Apr 19 13:56 kern.log.gz
-rw-r----- 1 root staff    88437 Apr 19 13:56 syslog
drwxr-sr-x 4 root staff     4096 Apr 19 13:56 tables

If the systemd service is enabled, the script runs automatically at boot and after hibernation. The collected data is stored in subdirectories of /var/local/acpi-gather-data/.
