Bug Description
I'm running Ubuntu on a Dell Inspiron 6400 with a 14e4:4328 "Dell Wireless 1500 Draft 802.11n WLAN Mini-Card". Running "rmmod b43" always hangs. So far I have only tried it while connected to a wireless network. I immediately disconnect from the wireless network, so it seems module removal does begin. But the rmmod process never finishes and is unkillable. The hang seems indefinite, and a normal reboot is not possible, the rapid ctrl-alt-del systemd emergency reboot is impossible, and only a Magic SysRq reboot works.
This worked in Ubuntu 17.10, but always fails in Ubuntu 18.04.
(I was unloading the module before suspend due to occasional problems after resume. I tracked this down when wondering why suspend was hanging. Even running the "rmmod b43" on its own without suspend happening causes the hang. Right now I disabled that automatic unloading.)
