Greg,

 

Has something changed in the PCI code in the Linux-next tree – 2.6.39-rc1-12
with

regards to irq allocation? Earlier (a few weeks ago), the vmbus driver would
get the irq allocated as part

of it being now a pci driver. Currently, however the system is setting pdev->
irq to

0 and needless to say, request_irq() is failing.

{sigh}  Please fix your email client...

Anyway, I have no idea, please use 'git bisect' to track down the
problem commit that causes this.

thanks,
