Just take the x86-64 UP config from FC3's latest errata kernel. I haven't booted it yet. A question, though: why do you comment out the DMPS timer in drivers/char/vt.c? Does it cause any problems? I applied the -RT tree after the multiconsole patch and I had to modify those four chunks manually. Best regards, Zoltán Böszörményi
