Argh. Thats what I get for not paying attention. :( I must have glanced over Alans posting and not registered it. ;(
Oh well, I will try and recompile .18 with the .14 irq.h and see what that gets me. ;)
for those who missed it, here is the post:

And from Alan in this thread:

Any ideas when/if this will get fixed? Is there anything we can do to help track it down to a hardware or software problem?
