The problem
We have an Adaptec 6805E card in an Intel Q67 / Core i7 server running Proxmox 1.9. Whenever and USB device is plugged in or removed (in our case the data center's KVM-over-IP console), there is a kernel error and the PCI bus hangs after that (extremely slows it down). It seems the Adaptec controller and the USB controller share the same IRQ.
Problem appears on all of our kernels, and only a hard reset solves the problem. Has anyone experienced this?
Others reported similar issues (not necessarily with OpenVZ kernel):

(remove spaces)
There are a lot of boot options regarding ACPI and IRQs.

We can't really test these on a production system. Anyone know what to do?
