[Xen-users] Server crashes while starting a domain with pciback.hide

["Martin Hierling" <martin@xxxxxxxxx>]

Hi,

one of my DomU crashes some time after booting (from 10sec to 12h). Unfortunately it crashes that bad, the complete server needs a hard reset.
the last thing i see with dmesg before it hangs:
PCI: Enabling device 0000:00:
12.0 (0000 -> 0002)
ACPI: PCI Interrupt 0000:00:12.0[A] -> GSI 17 (level, low) -> IRQ 18
That is the device i routed through the domU with:pciback.hide=(00:12.0)

So, any ideas why that happens and how to stop it....?
