Could you dump the stacktraces of other ipro1000 related threads? It's not clear in which state

the driver is when this panic happens.

Has this happened after the mbuf overrun fixes & mbuf refcounting?

Han't had a chance to test it and it happened only twice within 2 weeks. So let's assume it's been fixed, I'll reopen if needed :P

Happened again on boot after update to hrev52185.

comment:9 by dsuden, 6 years ago

We have kind of a "desperate" need for this driver to be stable. Hoping we can get there!

comment:10 by waddlesplash, 6 years ago

@dsuden, is it happening for you on real hardware? AFAIK nobody has seen this outside of VMware.

comment:11 by dsuden, 6 years ago

Yes, I get it fairly regularly. So do some of my customers. I don't think I have a screen grab remaining, but I'll look.

Found one.

That's #12567, which is completely unrelated to this ticket (and was already fixed in hrev51603.)

comment:14 by waddlesplash, 6 years ago

@dsuden, can you find me on IRC, please?

At any rate, regarding this actual ticket: It appears that the IRQ setup where the task is created and queued happens before the IFP is initialized: ​http://xref.plausible.coop/source/xref/freebsd-11-stable/sys/dev/e1000/if_lem.c#695 (allocate_irq enqueues the task, setup_interface initializes the IFP), so this appears to be a bug in FreeBSD code. I'll ask around.

Should be fixed in hrev52250.
