Re: Losing interrupts

Hello,
First, thanks a lot for the work done and still done for tackling the latency
issues in the kernel.
I'm interested in this area, and want to do some testing as well.
Lee Revel, could you please sent me the changes you made for measuring
interrupt times to me?
I've collected as well some preempt stuff, here it goes: (I've send them also
to Andrew)

I've used the voluntary_preempt patch, but it looks like there's no
difference. Both with/without kernel preempt and with/without
voluntary_preempt I'm getting the same results.
I used ck6 which includes all patches from Andrew as well.
I don't know if it is usefull, but I attached the startup dmesg log.
Thanks a lot, and hopefully you can do something with this information.
