Re: NVIDIA-installer for 5336 incompatible with Debian/Woody and 2.4.25 kernel



I did not include all details of the bug, but the modules never executes
because it can never link due to an unresolved reference to smp_num_cpus
from the 2.4.25 kernel.  I don't see how the recommendations (shown
below) from the NVIDIA docs have anything to do with this problem.
I don't have stability problems, I simply cannot event start it up since
it won't load at all !!

o I/O APIC (SMP)
        If you are experiencing stability problems with a Linux SMP machine 
        and seeing I/O APIC warning messages from the Linux kernel, system
        reliability may be greatly improved by setting the "noapic" kernel
        parameter.

o Local APIC (UP)
        On some systems, setting the "Local APIC Support on Uniprocessors"
        kernel configuration option can have adverse effects on system
        stability and performance.  If you are experiencing lockups with
        a Linux UP machine and have this option set, try disabling local
        APIC support.
