Yes, we know. This box has been running forever, always upgraded to the latest Fedora, and we recently upgraded the hardware to the Ryzen from a non-64-capable P4. That's why it's 32b. We will upgrade it to 64-bit during next scheduled downtime in a month.

Maxim: I think your problem is different from this bug. From everything I've read everywhere, the mwait and/or idle:typical tweaks always solve this bug. You've done even the esoteric stuff like nocbs and voltage override and your problem remains. Might (must?) be something else.
