Hum, but I do in fact see the same thing he sees on a VT. A dmesg
command from a VT  takes around 20 seconds to display. The same in a
konsole takes a fraction of a second.
So your probably right that my vi problem in a konsole is a different
issue. I do see the same thing as the OP does though. I just figured
they were probably related.

Changing fonts doesn't change anything though. I normally use the "Misc
Console" font FWIW.
