If you're running a 6.7 stable kernel, my patch has just been added to

However, lockdep has reported an issue with it:

This new report has not yet been properly understood, but FWIW I've
been running stable with my patch for over a month now.

Christian got an actual soft lockup, not just a lockdep warning, tho.
Christian, could you run the stack trace thru scripts/decode_stacktrace
and tell us which loop it's stuck on?
