I have reproduced this. Anything that causes lots of text to fly by quickly in
gnome-terminal can cause this lockup when using kernel-2.5.x.
Workaround: If you start a process that has lots of text flying by, but minimize
the window, it wont lockup.
I have reproduced this - even running "make menuconfig" locks up the terminal,
when it is vertically maximized.
However - I've first experienced this after booting to 2.6.0-test1 kernel
I was running the standard 2.4.x kernel when I saw it.
According to linux-kernel mailing list, this is an application bug uncovered by
the new O(1) scheduler.
It sounds like this is an old kernel problem. I'm going to close the
bug, but if people are still experiencing problems using recent
packages, please feel free to reopen.
