Is it just a matter of adding linux-crashdump as a dependency?

Also needs to upload the panic log from /var/crash/
Maybe leverage apport? It already has a hook for linux-crashdump.

Manually trigger a panic to see how it works:
echo c > /proc/sysrq-trigger

There are a few things that should be considered.
= Setup =
- the linux-crashdump need to be installed.
- kdump should be enabled by /etc/default/kdump-tools or dpkg-configurate.
- kexec-tools will be installed, but we don't want kexec-tools handle reboots, only use kexe for kdump.
- the system needs to have enough memory to load the kernel and save the crash file, the current default settings is 512M-:192M. It may not enough to dump the file. I think Ubuntu should change it using auto[1], and does not store any crash on a machine less than 4G memory.
- we may consider to use kernel panic to capture other sockup issues[2].
= Bug report =
- there are several tools can be used to submit the crash file to launchpad. But I think it would best to use a checkbox test job capture the crash file, and use apport via qabro to submit the bug to launchpad.

If Checkbox has a dedicated job that captures the kernel crash log and put it in Checkbox's $PLAINBOX_SESSION_SHARE directory, then it will be captured by QABro when filing a bug, since QABro currently archives the most current Checkbox session on the device and sends it over to Launchpad.

Hi Pierre,
Could you help to investigate that captures the kernel crash log from /var/crash/ directly when QABro file a bug? Due to it seems need more effort to determine when should the job puts the kernel panic log to Checkbox's $PLAINBOX_SESSION_SHARE

Summary
Description
To collect kernel panic when userspace processes are frozen, we can use crashkernel to collect log: $ sudo apt-get install linux-crashdump
And the panic log will be put in /var/crash, if a kernel panic ever happened.
