Bug Description

As discussed in mail, we have rather low yield (<50%) for LAVA builds due to thermal issues. There was some discussion how to investigate/improve this (to be filled in).

Around end of April, build were switched to lava-panda-usbdrive queue, which kinda improved success rate. Underlyingly however, gcc testsuite didn't finish completely due to OOM, and benchmarks are not supported on that config (because it doesn't run custom validated kernel).

On May 15, it turns out that CBuild machine (toolchain64) was resetup from scratch, and LAVA builds regressed (stuck in queue). Investigating.

It appears that we're taking another route to cbuild builds, so this is not Critical.

We decided to go different way - utilizing Jenkins and A15 boards.
