I am aware of that. Here's the latest in my fight: I got one server, which
I'd updated but not rebooted, and it's still on 358-18. I yum downgraded
kmod-nvidia and nvidia-x11-drv to what it had been running, 325.15-1, and
it's happy as a clam (after I reloaded the nvidia driver). BUT, I note
that modinfo shows
/lib/modules/2.6.32-358.18.1.el6.x86_64/weak-updates/nvidia/nvid, which is
a link to /lib/modules/2.6.32-358.el6.x86_64/extra/nvidia/nvidia.ko. I
find this... odd.
Now, running the new 431.5.1 kernel on the other server, the one that's
been rebooted, and I'm still fighting, I did the same... and see
/lib/modules/2.6.32-431.5.1.el6.x86_64/weak-updates/nvidia/nvidia.ko ->
/lib/modules/2.6.32-358.el6.x86_64/extra/nvidia/nvidia.ko
THAT does not look right at all.
dmesg shows
NVRM: loading NVIDIA UNIX x86_64 Kernel Module 325.15 Wed Jul 31

At least I've got one back. As a last resort, I can reboot to the older
kernel and see if that works with this version of kmod-nvidia, but I'd
*REALLY* like to have the new kernel
mark
