Comment 85 for bug 332270

I have two machines with this issue, both using LVM2 plus 3ware raid card. One of the machines don't have any alternative way to boot then I install a fresh jaunty to another hard disk from my internal mirror using usb netboot, initially I can boot into the new jaunty because I forgot to enable the raid volume( I have boot manager to hide disk volume), but after I enable the raid volume thus also enable LVM2 the fresh jaunty refused to boot. Finally I have to downgrade the udev(and devmapper) to 137 to get access to my LVM2 volumes. I will send the logs later.
