Ok, never heard of that one before, but I have removed Rich-Text

I don't see anything in particular that gives me any hint as to what
went wrong in dmesg other than it didn't come up. This is what I see

Ok, Thanks for this tip. I followed this with the system running
normally as I want. But whenever I make this 1 change in the Kernel
config, it stops the networking from working. The change I'm trying to
make is change the 'Timer Frequency' of the kernel from 250Hz to
1000hz.
If I do that and save the configuration without ANY other change and
then compare the .config.old and .config, I see a whole bunch of other
stuff changed with respect to audio/sound and what not. Then when I
build the kernel, the networking/bonding all fails to start. Here's
the diff between the two files.

Can anyone see what is making it fail? Note, I have ONLY changed the
Timer Frequency and nothing else
Thanks SO much
