Corey,

Ok, thanks for checking. I think rc1 is still early in the release cycle.
I am sure you problem will get fixed for final 2.6.26. What is annoying right
now is that you cannot test. But I suggest you stick with 2.6.25 and figure out
out to implement pfm_arch_resend_irq() which is important.


Thanks.
