2 - unit test minimal cpu (486), sigill
3 - add kernel oops detection to 90{1,2} kernel boot testing
4 - minimal minitrd RAM unit test
5 - maybe scale timeout w/ host and qemu perf
6 - furher refine arch matching for ppc64le
7 - sync -cpu w/ t2 arch OPT
8 - sync qemuargs -M w/ t2 kernel conf
9 - test t2 2nd stage w/o console=hvc0 to auto-detect
