| |
I can't seem to run a SMP 2.5.17 kernel on a UP machine, it locks up during the boot process. In talking to Jack Vogel, he suggested I make the following patch, which seems to solve the problem for me. In looking at the code, I have no idea of why this seems to work, so there probably is a better fix out there.
Any suggestions?
thanks,
