Turns out the kernel used by the reporter is not vanilla, as zfs is
involved -- and due to that the reporter is not even able to check if
mainline is still affected. I'll thus remove this from the tracking.
Sorry for the noise.
In case anyone nevertheless cares: The bisection result from the report
was 0c7ffa32dbd6b0 ("x86/smpboot/64: Implement
arch_cpuhp_init_parallel_bringup() and enable it") [v6.5-rc1].
This time on a Intel machine. Mario's "Fixes for s3 with parallel
bootup" patch-series[1] (the one were abandoned because things turned
out to be a BIOS bug affecting some AMD systems) apparently resolved the
problem for the reporter.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

Everything you wanna know about Linux kernel regression tracking:

If I did something stupid, please tell me, as explained on that page.
#regzbot inconclusive: kernel used by the reporter is not vanilla
