That is plausible, given that bisection has narrowed things down to somewhere between v6.5-rc5 and v6.5-rc6. And it is quite conveniently currently on a bad commit. Sometimes you get lucky. ;-)
So pulling in those commits from -tip, currently headed by this one:
d80c3c9de067 ("x86/srso: Explain the untraining sequences a bit more")
Then merging them with the current bad commit gets me a successful run. Thank you!!!
Thanx, Paul
