Since the kernel suggests trying two pci= options, I attach also the (somewhat different) dmesg output with both of them supplied. This makes no difference to the broken driver and no difference to anything else that I can see.
"irqpoll" and "irqfixup", to reiterate, cause a complete system hang after the keyboard driver loads (this is before initramfs begins executing, even) ** Attachment added: "dmesg with pci=routeirq pci=assign-busses" http://librarian.launchpad.net/5204196/dmesg.routeirq.assign-busses -- [madwifi] Atheros AR5005G doesn't work with 2.6.19 (fine with 2.6.17) https://launchpad.net/bugs/73828 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
