Just as a datapoint for debugging at least qemu/arm is getting coverage in CI systems (KernelCI is covering a bunch of different emulated machines and LKFT has at least one configuration as well, clang's tests have some wider architecture coverage as well I think) and they don't seem to be seeing any problems - there's some other variable in there.
For example current basic boot tests for KernelCI are at:
https://linux.kernelci.org/test/job/mainline/branch/master/kernel/v5.17-1442-gb47d5a4f6b8d/plan/baseline/
for mainline and -next has:
https://linux.kernelci.org/test/job/next/branch/master/kernel/next-20220322/plan/baseline/
These are with a buildroot based rootfs that has a "Saving random seed: " step in the boot process FWIW. [unhandled content-type:application/pgp-signature] | |
