Dom0 and Domu sharing a physical IRQ results in eventual crash
I have one xen machine where dom0 libata and pcibacked domU eth0 share a physical IRQ. I thought that the disk was bad (cause the system was crashing and giveing me disk errors) and replaced it with an IDE disk connected to a pcibacked SATA-IDE combo card. Problem seems to have gone away. The machine runs stably and hasn''t crashed yet. Now I have another machine where I pciback usb.
