Under KDE I went into floppy and made rm *. After this keyboard was lost - 
even CAPS LED did not respond to keypress. I stil could use mouse to start 
new windows and even execute some commands by copy'n'paste from available 
text :)

Attempt to exit KDE ended in black screen. I had to press reset; after that 
the following text was found in syslog (slightly abridged, it had much more 
those "floppy driver state"s).

Floppies are not that robust, everyone knows it. It is rather unfriendly to 
handle media errors in such manner :)
