WARNING at kernel/irq/resend.c:70 check_irq_resend() on OSK

[Dirk Behme]

Frist, thanks for updating the kernel! Tested on OSK, everything looks 
okay.

While booting on OSK, I get stuff below. Any idea? Note that kernel 
goes on booting and nothing feels broken.

Best regards

Dirk

FWIW, I see this on 2430 too.

This is from  some temporary debug code added[1] that made it into
2.6.23-rc2, but was recently removed by Linus[2]

Kevin,

Were you seeing it consistently on today's GIT after compile fix ups?

I'm not.  But, seems like I still have some hacks in the resend code.  Back on 19 I had some tick issues and I created a patch which I applied to my local git.  I've not bothered to remove those yet.  Don't know if they are fixing/masking something.  Why don't you shut off Dtick and see if you still have it.

I tried with HRT+NO_HZ and without both, and I see the same backtrace
consistently.
