It's  unclear to me why  'sysrq' kernel support could change anything.
Test suite does  echo 't' to sysrq - in case of timeout - but purely to
capture machine state for analysis.

Also - lvm2 test suite is not a user-friendly installable app and certainly 
does require some 'know-how' to be executed in some usable way  - so it takes
some few more steps - like ensuring there are no other running daemons like 
lvmetad, lvmpoll and dmeventd in the system. Proper udev rules needs to be 
installed (to get cookie confirmation from udev) and of course whole test 
suite needs to be run as 'root'.

So it's mainly targeted to developers.

But it's great more people try to use it.

So - instead of checking whole test suite report result from:

# cd test
# make check_local T=basic VERBOSE=1
