Comment 2 for bug 430011

When I catch Grub in time, booting into 2.6.28-11 is sufficient to avoid the dongle issues.

I'll try to bisect it a bit further when I get back to the boat, but it'll take some time as it takes between 6 to ~0 minutes for the serial stack to oops (after which a full reboot is required to get the dongle functional again).
