>Description:
The SCSI and ATAPI drivers do not have detach routines
(i.e. in the cfattach struct).
This means that if a detachable device, e.g. a PCMCIA SCSI
card or USB disk, is unplugged the kernel will panic.
This is not nice.
>How-To-Repeat:
See above.
>Fix:
Well, as a first step the attach routines should be added.
I'm not sure what should be done if a disappearing disk is
mounted.
