Hi,
This is my first post on Majorodomo so please excuse any misdemeanor.
I have been running a CCTV system under Linux, lubuntu 12.10 for 3
years. I use 6 analog cameras attached to a techwell 6800 card. I use
package motion 3.2.12-3.2.

I have been using the TW68-v2 driver from github. The system has run
flawlessly for three years, for months at a time without reboot.
For the past 2 years I have been trying to upgrade to a later version of
lubuntu with no luck. I have never been able to compile the driver under
later versions on lubuntu. Too many errors and attempts to list here.
I thought my luck had changed with Linux kernel 3.18 and above. TW68 now
included. But it does work correctly. I am now trying 3.19 kernel, no
change. So I tried the version on linux-media. I still have the same
problems.
Before I go into details of the error I have some question about
confirming I really am running the latest and greatest version of tw68.
I would hate my first post to be a user error.
How do i check I am running the right version of tw68. Here's my attempt
to validate what is running.

Why is the size of the module reported in lsmod different from what is
in /lib/modules......
Can I be sure I am running the Hans Verkuil, William M. Brack version
rather than version rather that any supplied with 3.19 kernel.
Once i have eliminated a user error I post details of the problem I have.
Thanks for reading this and hope you can help,
Tony.
