Looking at this, I see debugfs mounted, I see LKDTM enabled, but I see
the console freak out just as lkdtm starts:

Is a kvm test running at the same time? It just looks like the entire
console goes silent (which would certainly make the lkdtm tests fail)

Similar happens here, only this time it seems to be gpio tests?

# ./gpio-mockup.sh line 89 ./gpio-mockup-chardev No such file or

...
[ 407.481225] test_bpf: #0 TAX jited:1 63 62 132 PASS
The console seems broken for over 40 seconds?
