from your logs I cannot deduce anything useful, but in our CI I've got similar issues
since the 10/12th of Feb...
TAP version 13
1..71
# selftests: lkdtm: PANIC.sh
# Cannot find /sys/kernel/debug/provoke-crash/DIRECT (missing CONFIG_LKDTM?)
not ok 1 selftests: lkdtm: PANIC.sh # SKIP
# selftests: lkdtm: BUG.sh
# Cannot find /sys/kernel/debug/provoke-crash/DIRECT (missing CONFIG_LKDTM?)
so I suppose this and a bunch of other (probably new) tests are simply
missing a bit of CONFIGs... (but I have still to look into this properly)
(not sure if this also is your case either...)

Hi Kees,
Any ideas on what this is about? Missing config or something else?

In the first case, I'm not sure what's happening -- the logs don't seem
to show anything, but the lkdtm should be available (from the boot log).
In the second case, yes, it looks like missing CONFIG_LKDTM (the test
even has a "config" file). Either CONFIG_LKDTM=y or CONFIG_LKDTM=m will
work (the test running will attempt to load the lkdtm module if it's
missing).
A final option is that either the debug filesystem isn't mounted, or is
mounted somewhere "non-standard"? (I'd expect a lot of things to fail...)

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

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?
[ 363.276824] kselftest: Running tests in lkdtm
# ./gpio-mockup.sh line 89 ./gpio-mockup-chardev No such file or

# -1,32,-1,32,-1,32
...
[ 407.481225] test_bpf: #0 TAX jited:1 63 62 132 PASS
The console seems broken for over 40 seconds?

Did you solve this with loading lkdtm?

Sorry I lost track of this thread....tested now on v5.6rc3 on arm64 on a local
setup (not proper CI) with CONFIG_LKDTM=y and solves the above issue. (missing CONFIG_LKDTM?)
Looking at the general run though I have anyway a bunch of SKIP similar to Naresh
./run_kselftest.sh 2>/dev/null | grep "SKIP"
not ok 1 selftests: lkdtm: PANIC.sh # SKIP
not ok 6 selftests: lkdtm: LOOP.sh # SKIP
not ok 7 selftests: lkdtm: EXHAUST_STACK.sh # SKIP
not ok 8 selftests: lkdtm: CORRUPT_STACK.sh # SKIP
not ok 9 selftests: lkdtm: CORRUPT_STACK_STRONG.sh # SKIP
not ok 15 selftests: lkdtm: UNSET_SMEP.sh # SKIP
not ok 16 selftests: lkdtm: DOUBLE_FAULT.sh # SKIP
not ok 18 selftests: lkdtm: OVERWRITE_ALLOCATION.sh # SKIP
not ok 19 selftests: lkdtm: WRITE_AFTER_FREE.sh # SKIP
not ok 21 selftests: lkdtm: WRITE_BUDDY_AFTER_FREE.sh # SKIP
not ok 26 selftests: lkdtm: SOFTLOCKUP.sh # SKIP
not ok 27 selftests: lkdtm: HARDLOCKUP.sh # SKIP
not ok 28 selftests: lkdtm: SPINLOCKUP.sh # SKIP
not ok 29 selftests: lkdtm: HUNG_TASK.sh # SKIP
not ok 59 selftests: lkdtm: REFCOUNT_TIMING.sh # SKIP
not ok 60 selftests: lkdtm: ATOMIC_TIMING.sh # SKIP
BUT, if I look at one LKDTM test script
(lkdtm/USERCOPY_STACK_FRAME_TO.sh):
...
# If the test is commented out, report a skip
if echo "$test" | grep -q '^#' ; then
...
and in fact:
root@sqwt-ubuntu:/opt/ksft# cat lkdtm/tests.txt | grep ^#
#PANIC
#LOOP Hangs the system
#EXHAUST_STACK Corrupts memory on failure
#CORRUPT_STACK Crashes entire system on success
#CORRUPT_STACK_STRONG Crashes entire system on success
#OVERWRITE_ALLOCATION Corrupts memory on failure
#WRITE_AFTER_FREE Corrupts memory on failure
#WRITE_BUDDY_AFTER_FREE Corrupts memory on failure
#SOFTLOCKUP Hangs the system
#HARDLOCKUP Hangs the system
#SPINLOCKUP Hangs the system
#HUNG_TASK Hangs the system
#REFCOUNT_TIMING timing only
#ATOMIC_TIMING timing only
so only two of the above tests are in fact unexpectedly skipped.
not ok 15 selftests: lkdtm: UNSET_SMEP.sh # SKIP
not ok 16 selftests: lkdtm: DOUBLE_FAULT.sh # SKIP
I've not investigated further as of now.

Yeah i see this case at my end also.
my two cents,
I have two comments,
1) shell check
2) I see the debugfs mounted and test required details are available
in a given path.
1) Shell check show these warnings

Yup, that is operating as expected. :)

These are x86-specific, so that is correct as well.
Thanks for following up!

I'll fix these up; thanks for the suggestions!

This is the part that is failing and I don't know why.
clear the kernel event log:
dmesg -c
trigger the kernel event:
/bin/sh -c 'cat <(echo BUG) >/sys/kernel/debug/provoke-crash/DIRECT'
dump the newly added event logs into a file (set -x doesn't report
redirection to /tmp/lkdtm-r5yZ7K):
dmesg -c
It seems /tmp/lkdtm-r5yZ7K is empty?
