Sure. Let me know if you find anything.

I managed to reproduce. With "threadirqs" and without
"tsc=reliable". I see tons of spurious TIMER softirqs.
Investigation begins! I'll let you know.

Gentle ping. Any new findings about this issue?

Yep, I'm working on a series to reduce timer softirqs. I'm almost
done, should post it soon.

Great!

Looking forward to it.

Best,

Juri
