Interrupt storm detected on "irq18: uhci2"; throttling interrupt source

Would increasing the storm threshold help (especially disk
performance)? Guess I'm looking for any mitigation that might be possible.
There's no easy answer on this. You'll have to run your own benchmarks. If
you don't need USB, then you may just want to leave it out of your kernel
which might help some.
OK, thanks for the info and suggestions. Regrettably, leaving out USB
isn't an option for us. I'll schedule some benchmarking for all that
ample free time I have :-)
Best,
