Is vanilla 2.6.31.2 compatible with Fedora 11's userspace?

[chrisr]

I've just compiled a 2.6.31.2 kernel, and tried to boot it against a Fedora 11 userspace environment, but X is refusing to initialise. The kernel mode-setting seems to start OK:

But there's no Plymouth. The dmesg log ends like this:

Is the X-server's radeon driver just too old, please?

Thanks,

You need updated libdrm_radeon, xf86-video-ati, and mesa to use 2.6.31.x with F11.

Thanks; I take it that RawHide (F12) will be new enough? Or will RawHide need a 2.6.32 kernel? Come to think of it, assuming that 2.6.31.2 does work with RawHide, what are the prospects of 2.6.32 working with F12?

Cheers,
Chris

F12 should be fine.

[chrisr]

F12 should be fine.

*Sigh*, I've got the Fedora 11 userspace running against 2.6.31.2 ATM by adding "modeset=0" to the initrd's init script. But F12's xorg-ati driver is refusing to compile against F11's xorg-x11-server-devel-1.6.4-0.1.fc11.i586 package. Something to do with the number of arguments in the xf86GetDefaultModes() prototype. So I'm guessing that the X server itself needs upgrading too.

It will probably be simpler to upgrade to F12 itself - in one month's time?
