The kernel_command_line variable is not needed...

... and you can just use self.KERNEL_COMMON_COMMAND_LINE here.

Nitpick: it's more Pythonic to format strings than to concatenate
them.

Another nitpick is, given that image is pinned down, maybe attempt to
match against the entire line?

  init started: BusyBox v1.24.1 (2017-05-15 09:57:00 IST)

Because of the other discussions about tests and timeouts, this is
what I get on a first run (having to download the images):

 (1/1) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (27.49 s)

And then, a pretty consistent < 8s mark using the resources from
cache:

 (01/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.55 s)
 (02/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.35 s)
 (03/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.40 s)
 (04/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.60 s)
 (05/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2:

 (06/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.33 s)
 (07/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.35 s)
 (08/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (6.38 s)
 (09/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.39 s)
 (10/10) 
tests/acceptance/boot_linux_console.py:BootLinuxConsole.test_arm_emcraft_sf2: 
PASS (7.44 s)

It'd be nice to know the average test execution time on real/typical
hardware, and with that, starting to adjust expected timeouts.  Anyway:
