Subject"Badness at kernel/irq/resend.c:70" on boot - via-pmu?
Date
Hi Linus,

I got the message below on boot with 2.6.23-rc2 on my PowerBook.

I've Cc'd some powerpc folks because via_pmu_interrupt is in the
Macintosh PMU driver.

Hmm, I just looked back in my logs and I also got that message with
commit 7a883eaf62f4b943ebec738ce3b0796c67ef5d32. Before that I used
6c8dca5d53f95009d4fff00195bf38f277dc4366 and there was no badness
message logged by that one. There's only about 480 commits between
those two, so I can bisect it if necessary.

The call traces differ, so here are both messages.

v2.6.23-rc2:
