From all those links it seems quite a lot of users with Dell machines are affected by this problem.

Thomas, turns out that bisection result was slightly wrong: a recheck confirmed that the regression is actually caused by 45e34c8af58f23 ("x86/smp: Put CPUs into INIT on shutdown if possible") [v6.5-rc1] of yours. See https://bugzilla.kernel.org/show_bug.cgi?id=217995 for details.
Ciao, Thorsten
