[ltt-dev] ltt-dev Digest, Vol 12, Issue 4

[Shouwei Li]

HI, All:
Thank you very much for your quick reply!
I have put the config file in the attachment. Please help me to check it.
If the modules have been build in to kernel correctly, why I can not
find the by this command:
# lsmod | grep modulesName
Now I am not sure whether I have compiled the kernel correctly, of
course I don't knwo What should I do next?
Thanks a million!
