Filing this as a note for the arch teams rather than expecting maintainer to handle (but help welcome!), but we had a few RCU hangs in a row on both machines and a liburing test was spinning on both of them with a large amount of CPU time.
Is this still the case with 2.6 version?
Please test with 2.7-r1.
I don't think this happens on timberdoodle anymore but it does still on sparc.
