Just discovered these messages in /var/log/messages, while looking at the USB problem I just posted about, separately.

but I cannot find anything relating to Nvidia that has a 331.49 version number. "yum list installed | grep 331.49" returns no hits "yum list installed | grep 331.[0-9]" returns ONLY hits on 331.67. "find 331" finds lots of things, but none of them is 331.49.

So, I'd be appreciative if someone could shine a light on this for me.

thanks!

You updated the NVIDIA driver/kernel module while the old one was loaded into the kernel.

As root: # telinit 3 # rmmod nvidia # telinit 5

That could well be the problem,... I tend to lose track of such things sometimes.

for some reason telinit 3 went bonkers so I ended up doing a reboot which should (and seems to have) also solve(d) the problem.

Thanks!
