1 commit: 7d6992a
rebased to current tip of Ghaf main without conflicts: 5c27067

platform: Lenovo X1 Carbon; flash script

• ci-test-automation suite: ok
• starting apps: ok
• regression / ad-hoc testing: ok

works:

• basic browser usage is ok

notes:

• it is not clearly stated what & how to check; and then what should be expected, so in testing:

  • consumed 1.5G of memory from chroumium-vm: dd if=/dev/random of=file
  • opened 6 (or 7) youtube tabs with random movies, full quality, x2 speed

  -> browser crashed in about 15 minutes

issues on Lenovo X1 Carbon:

• it is possible to crash the browser; however it is not clear how much stress should it handle
