Subject: [boot time] Call for boot time data!!

Linux developers and users,

I'm trying to build
a system of reference value files for an initcall duration regression test I'm writing for the Linux kernel).

If you have a machine, or particularly any embedded dev boards (like a beagleplay, beaglebone (*), raspberry pi, etc.), it
would help me out a lot of you could run this tool: grab-boot-data.sh
which you can get from here: https://birdcloud.org/boot-time/Boot-time_Tools

This tool grabs a bunch of information about your machine, including, most importantly, your boot-time
kernel messages, and sends them to me.  If this sounds too much like a security nightmare, you
can just not heed this call, or there's an option (described on the page above) to review the data
before you send it.

Optimally, I can get the best information if you run the tool with 'quiet' and 'initcall_debug' options
on the kernel command line, but if that's too hard to configure, you can just run grab-boot-data.sh with the '-s' option.
Please run the script sometime shortly after boot of your machine.

Data for any machine, running any recent kernel version, is fine (any kernels pre 4.0 are not that useful).

You will need to make up a lab name and a machine name for the machine or board you are reporting on.
I use 'tims_lab' and 'bp1' for a beagleplay in my possession.

The tool will send data to https://birdcloud.org/boot-time/Boot_Data

If you can send data for just one machine, that's great.  If for multiple machines, that's even better.

I'll be reporting on the boot-time regression test at ELC in June, and any data I can gather in the next
few weeks will really help me with progress towards the test and my talk.

Thanks.
 -- Tim

P.S. If you see any problems running grab-boot-data.sh, please report them to me.  Thanks.
