Reloading hpilo will allow the IRC kdb/mouse to function correctly. I've been struggling with what to do about this, removing the pci_disable_device() from hpilo will "fix" the problem, but that is clearly a hack. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
