Hmm... it looks different from that bug - in that case the root cause was sysfs_make_dirent failing, presumably when the sysfs node for the device was being set up, by unplugging and re-plugging the device a lot. Here it's oopsing when the node is being removed, after it's been in use a while and unplugged only once. But yes ppp may not have anything to do with it. I'll try it on an older kernel to see if I can reproduce there...
