Weird. I'll pretend I never saw this as hopefully missed-irq will be gutted very soon.
Fwiw, it does appear to be a false positive. Request was queued less than 2ms ago, and the signaler is R -- so has been woken.
If you remove the check, it can't fail any more... We fundamentally reworked how fences are signaled, and threw this out as dead code.
