Xen, IRQ-sharing and PCI passthrough
...ollows:
1. Put a PCI card in the machine and make sure it shares it''s IRQ with
another one. In my case it is a RIO Specialix card but I doubt this
makes any difference.
2. Map the card to a domU and use it there. In the RIO case this
requires loading a kernel module and running a "rioboot" tool.
3. Power down (either shutdown or destroy) the domU without stopping
the card (here: "riostop" and "rmmod rio").
The resulting kernel stack trace is as follows:
[ 337.409057] pciback 0000:04:06.0: enabling device (0000 -> 0003)
