Just ran it on physical arm32 and arm64 (Renesas APE6EVM and
Salvator-XS), and the test crashes there, too.

kunit_kernel.ConfigError: m68k is not a valid arch, options are
['alpha', 'arm', 'arm64', 'i386', 'powerpc', 'riscv', 's390', 'sparc',
'x86_64']
Will look into adding m68k support ;-)
But the issue can easily be reproduced using
".../tools/testing/kunit/kunit.py run --arch=arm
--cross_compile=arm-linux-gnueabihf- --raw_output=all --kunitconfig
./net/sunrpc/.kunitconfig" on current upstream[1]:
