Comment 21 for bug 401713

Again, with your patched version, everything went perfectly fine in Jaunty, I don't have your knoledge here, but, my gut instint tells me this is definetly an issue with the kernel 2.6.31 in Karmic, we should comment this to the kernel devs, it could be a disaster to have a non-working dmraid in Karmic due to this...

here it is the log with your patched version too:
