I also had to add irqpoll to the bootup (in /boot/grub/menu.lst, where it says "kernel ... vmlinuz ... ro". I haven't tried removing the option from xorg, but my Avaratec now works. I added the irqpoll since I got the message that IRQ185 wasn't being handled.
I think the irq "multiplexer" in the kernel confuses the display with the ralink card, or that the ralink driver is getting confused and wants to respond to display or conversely the card is pointing at the display IRQ. I think upping the debug on the kernel module and looking which IRQ it is trying to use might isolate the problem which I might try later. I'd also look for subtle changes with the IRQ master handling between 2.6.12 and the current kernel - including #def IRQ type things. -- Ralink Wireless USB/PCMCIA/PCI hangs PC https://launchpad.net/bugs/34902 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
