Looking at the log file that isn't password protected that's the last
line of output so it'll have hung trying to do the first test, based on
the log from another machine:

   https://qa-reports.linaro.org/lkft/linux-next-master/build/next-20250905/testrun/29777055/suite/kvm-unit-tests/test/debug-bp-migration-timeout-duration90s/log

it seems that should be

   ok 1 - selftest-setup: selftest: setup: smp: number of CPUs matches expectation

that's died for the version they're using.

My Linaro account appears to have been disabled at some point so I
can't access it either.  If this is affecting mainline presumably it's
been an issue in at least -next for a while.
