Description Pete Zaitcev 2000-08-09 00:11:56 EDT
If gpm RPM is installed, gpm attempts to run
on /dev/console rather than on /dev/tty0.
If console is serial with a kernel option,
gpm prints garbage to the console and loops.

gpm-1.19.3-5 from rawhide now has a patch to detect if it is running on a serial
console and abort.
