I believe that what happened is that I ran rmmod and the system ran modprobe at the same time, and they are deadlocked. I'm not sure of this though. I'm going to reboot now, and this problem may never show itself again. But, I thought I should report it when it did. Version-Release number of selected component (if applicable): kernel-2.6.1-1.43 modutils-2.4.26-2 How reproducible: Didn't try Additional info:
This was probably fixed a long time ago.
