Exclamation installation fails with general protection fault in nvidia kernel module

Trying to install either an older nvidia driver or the latest 9626 results in a general protection fault the moment the installer tries to load the module.

-> Kernel module load error:

Default Re: installation fails with general protection fault in nvidia kernel module

Does this reproduce if you're not using a Xen enabled kernel?

No, the problem goes away with a non-xen kernel.

Default Re: installation fails with general protection fault in nvidia kernel module

Then I'm afraid that this is expected behavior, as the nvidia driver doesn't currently support Xen.

Default Re: installation fails with general protection fault in nvidia kernel module

That's okay with me, but you are aware that with Fedora Core 6 this is the default kernel that gets installed? (Don't know if it depends on installing the Xen packages or that it is installed regardless, but I can assure you I didn't select anywhere which kernel I wanted, this was the one selected for me by the FC6 installer)

If you are not planning any support (yet), you might think about changing the installer to warn about this.

Default Re: installation fails with general protection fault in nvidia kernel module

The xen kernel is not the default kernel that is normally installed on any of the FC6 installations I've performed in the past few weeks. Also you're the first person running FC6 to report this problem, and many others have run into unrelated problems with FC6. So, I'd assume that you need to explicitly install xen to get a xen kernel by default.

Thanks,
Lonni

Default Re: installation fails with general protection fault in nvidia kernel module

I did select the Xen package during installation, which might mean that the xen kernel gets installed automatically, that's the only thing I can think of because I did not install it myself (and the FC installer does not give you any options about which kernel to install as far as I know).

Just wanted to warn you that Xen being a new interesting technology there might be many more people inclined to install it and you might face more problems in the future with people asking why it doesn't work.

That's why I suggested to put in a warning at least ;-)

Better yet, make sure it won't compile because there exist several repositories that have precompiled nvidia packages, also for xen kernels. I know, that's not your problem ;-)

Well I usually install with everything and when doing so it does install it with the xen kernel (it surprised me because I didn't want it.) Also I found xen supervised kernel laggy for some reason so I chucked it. I would have done this even if it would have worked with the nVidia driver.

Thanks for your feedback. I've opened an RFE to have the driver installer better detect Xen enabled kernels.

Would it be possible to open an RFE for support of Xen kernels?

Thanks!

Looking at this patch for FC5 http://www.nvnews.net/vbulletin/show...&highlight=xen it should be possible. Now to convince them to actually support it :-)

Xen support is currently under evaluation for a future driver release.

Thanks,
