Hi,
Symptom:
monitor:/mnt/1wire/10.FE771D020800 # cat temperature
cat: temperature: Message too long
I've updated my monitoring server from openSUSE 13.1 to 13.2, which broke
owfs. I had 2.9p5 before and also tried to update to 2.9p8, but the
problem stayed the same. Access using owdir, owget and owwrite works fine.
I've started owfs in debug mode, leading to the following output (error at
the bottom).

It might be related to the new kernel, but I'm not sure ...

Help! :-)
(and many thanks for owfs!)
kind regards,
