This is a problem in the input subsystem in the linux kernel. There are some locks that are not present that causes this in some cases when you disconnect the tablet (I get it on and off both when unplugging and suspending the laptop). I've had a look at it but not seen an easy way to add them though.. The only fix after one of these is a reboot (you might need to yank the power coord, at least I had to as my distro hung during shutdown). The whole USB-subsystem goes by the way... But the good side is that there are workaround for this. I'm not sure the user-space proxy device [linuxwacom-devel, Nov-06 'alternative way to support tablet hotplugging'] will help you here. It might be a small timing issue, and the user-space program might add sufficient delays that it won't make this happened. If that doesn't help, have a look at the wacomproxy (also a SF-project) kernel module that I guaratee does not have the kernel-oops problem (one of the two reasons it was written).
