Attempting an install of FC6 gives me the error message "Spinlock recursion" followed by a host of error messages. It appears just after hitting 'enter' to begin installation, before reaching any input screens. Linux rescue does not work either. Kernel options noprobe, acpi=off, nosmp all do not help. I've confirmed the install dvd is working. Google and LQ search hasn't turned up anything helpful. Does anybody have any ideas?
