Linux Virtualization - Apr 2011 - irq allocation for pci drivers

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.

Thanks,

K. Y

{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,
