Ah, so, that's why it's showing up now.  We probably have had the same
issue all along but it used to be masked by the softirq limiting.  Do
you care to revive the 10 iterations limit so that it's limited by
both the count and timing?  We do wanna find out why softirq is
spinning indefinitely tho.

Yes, no problem, I can do that.

Limiting it to 5000 fixes my problem, so if you wanted it larger than 10, that would
be fine by me.

I can send a version of my patch easily enough if we can agree on the max number of
loops (and if indeed my version of the patch is acceptable).

Thanks,
Ben
