>Description:
When a mounted block device is removed (tested USB CF reader and PCMCIA CF reader) the kernel panics.
This time I mounted the CF readonly which may be the reason I got a core. I can try to extract something from it but this should be easily reproducible on any system.

Removing a floppy does not cause such problems but in that case only the medium is removed, the floppy drive stays in the system,
>How-To-Repeat:
Attach an USB mass storage device or PCMCIA to IDE bridge, mount a device from it, remove it (detach)from the system.
