Could be. It might also be that that 'xl' never did it the same way
as 'xend' (meaning this might be a XenBus teardown change).

Note also that this is PV guests - and I think most of the testing
had been with the HVM guests with PCI passthrough. So it might be a
seperate issue altogether. Or that nobody tried doing PCI plug/unplug
in the past :-(

No. Let me of course try that.

No. A v3.10-rc4 with Xen 4.3 latest.

Is Debian Wheezy a 2.6.32 kernel?
