Re: "DV failed to configure device" for Quantum DLT4000 tape drive on Adaptec 2940UW, 2.6.0-test11

[Darren Dupre]

The backup just finished.. I unloaded the modules (doing "rmmod st aic7xxx"
exactly like that)

Now the kernel barfs this out at me (again, this is 2.6.0-test11)  right as
or after I unload the modules:
