FC2 / nvidia worked - once

[stray]

i installed FC2 on a test system yesterday. for some reason (i wish i knew, that's why i post this) the nvidia installer producted a perfectly good system. after editing xorg configuration, i played a couple of tuxraces and turned the machine off.

today, i tried the same thing with another workstation. the nvidia installer compiles the module without complaining, but on *this* machine, starting X with the nvidia module locks the machine hard.

i could dig into the different hardware configs, but if anyone has any idea or WAG what could be the reason for this strangeness, please post your theories.

ps: unfortunately i wiped the disk of the test machine already, but i could easily set it up again if anyone's interested in digging deeper into this.

It would be very interesting to know the differences in the hardware.. specifically whether they were the same architecture.. and used the same kernel? (smp?) The same video gpu or similar?
It is strange to hear that it worked at all.. that is definitely not expected.

Also.. are you quite sure that the system loaded the nVIDIA glx libs and not just the Mesa-libGL? It is possible to have the nvidia driver running.. agp support and everything, but still end up loading the Mesa glx -- this should have been noticeable since glxgears will produce around 1/10 or less the framerate if that happened. It is actually not use of the nvidia kernel module or X driver that crashes the system for me.. but loading the glx libs -- when loaded, even before they are used, the system goes down.

Currently, I'm running (FC1) with kernel 2.6.6-mm4, with 4k-stacks and config_regparm enabled and using patched nvidia driver 1.0-5328 (5336 locks for me on any 2.6 kernel). SMP is disabled (but might try it later to get more hyperthreading support) IO-APIC is enabled. glxgears reports approx. 1162 fps.

This is with a Geforce FX 5200.
