I was having problems installing FC4 on my machine. It was giving kernel panic.. pin_lock .. nota tainted error. So after searching I found a solution for installing. Passing ide=nodma argument.
After that I am successfully able to install FC4. But the system is performing very slow .
I tried removing ide=nodma while booting but it gave same error as while installing.
Same configuration machine at my office with FC4 is performing well.
M/C configuration :: P IV 2.66 Ghz, 512 MB RAM, 80 GB HDD (Hitachi)..
Is it because of ide=nodma argument i m passing at boot time???
