Subject: "Badness at kernel/irq/resend.c:70" on boot - via-pmu?
Date: Sun, 05 Aug 2007 15:22:01 +1200 [thread overview]
Message-ID: <87sl6ypsx2.fsf@briny.wgtn.ondioline.org> (raw)
In-Reply-To: <alpine.LFD.0.999.0708032031480.5037@woody.linux-foundation.org> (Linus Torvalds's message of "Fri, 3 Aug 2007 20:50:43 -0700 (PDT)")
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:
