Yes, switching first to 12.10 then to the still-supported 10.04 was our eventual workaround too - since Canonical clearly don't care about a bug that Canonical clearly introduced into an LTS. This is unfortunate. -- You received this bug notification because you are a member of Ubuntu Bugs, which

There is a solution or more of a shortcut to this problem. I tryied everything I could find in the internet and what I could come up with my own but only way to fix this problem was to updat OS to Ubuntu 12.10 which doesn't have this problem. -- You received this bug notification because you are

I have just tried again with 3.2.0-29, first disabling the Broadcom driver with jockey. I now get the oops in an untainted kernel - this suggests it is indeed something about the Ubuntu variant. Realistically, is anyone looking into this problem or going to look into this problem? I need to know w

Right, I've tested again. Current Precise kernel, 3.2.0.29, produces the oops. So the bug is still present. The interesting thing is that mainline kernel 3.2.0 for Precise, from the kernel PPA,*does not* show the bug - the Wacom connects just fine. So it's (a) something Ubuntu has changed from ma

I keep meaning to run further tests against various mainline kernels but not having the right combination of machine access and time. Would this be useful information at this stage, or do you have a good idea where and why this is happening? -- You received this bug notification because you are a
