Re: drivers can't be removed (device or resource busy)

[Justin Schoeman]

Try type 'dmesg' - if you see an oops message for nvrec, then it is the 
driver that generated the segfault, and the only way to unload it will 
be to reboot.  Otherwise, use 'lsmod' to find out if any modules are 
using the video module you want to unload.

This is with devfs, so in my understanding, the only v4l-related device 
files are in /dev/v4l, right?

lsof /dev/v4l/* yields nothing, but still, any attempt to remove the
video modules yields "device or resource busy".
How do I resolve this? I would be very unhappy if I had to reboot for
this ...
