Ok, it seems "irqpoll" option only helps with kernel-PAE.. if I boot kernel-xen with "irqpoll", it doesn't help and the console is messed up.. and the USB IRQ error is a bit different: http://pasik.reaktio.net/ibm-hs21-blade-usb-problem-07-with-xen-and-irqpoll.jpg irq 18: nobody cared (try booting with the "irqpoll" option) .. Disabling IRQ #18 and also hypervisor/xen symbols visible in the traceback.. instead of only the usb/interrupt stuff when running kernel-PAE. -- Pasi > I'm running RHEL 5.2 (2.6.18-92) atm. > > Any ideas how to fix this?
