Looking at this, I see debugfs mounted, I see LKDTM enabled, but I see the console freak out just as lkdtm starts:
[ 349.262263] kselftest: Running tests in lkdtm # 4 0x0000000000401014 ?? ??0 0x0000000000401014: ??_??0 # # 5 0x00007f9de1221a56 ?? ??0 0x00007f9de1221a56: ??_??0 # # 6 0x0000000000401399 ?? ??0 0x0000000000401399: ??_??0 # # madvise failed, failed,: _ # # addr 0x7f9de1000000 0x7f9de1000000: _ # # length 0x200000 0x200000: _ # # src_type 0 0: _ # # Testing guest mode PA-bitsANY, VA-bits48, 4K pages guest: mode_PA-bitsANY, # # Guest physical address width detected 39 physical: address_width # [FAIL] 11 selftests kvm vmx_dirty_log_test # exit=254
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?

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