Summary:                    /proc/zaptel/xxx doesn't work properly under Linux
2.6
Description: 
The code to generate the /proc/zaptel/xxx pages assumes it can write a
whole page in one go. This works with Linux 2.4. However, Linux 2.6 can
only accept 1024 bytes per write from a kernel module. The page an E1 with
all the channels configured and some errors showing exceeds 1024 bytes, and
the end gets chopped of.

The off and count parameters to zaptel_proc_read need to be used to get
this right. However, getting things right with changing data would be a a
pain. Ensuring pages never exceed 1024 bytes might be easier in the short
term. Changing ClearChannel to CC did it for me as a temp. measure.
