Hello Mr Haabendal,
sounds like a bug, which version do you use. Did you download the
tar.bz2 file from Sourceforge?

Hi
With ethercat debug, I see something like this:
# ethercat reg_read -p 0 0x1000 --type uint8
[ 29.104116] EtherCAT 0: Master debug level set to 1.
[ 29.147356] EtherCAT DEBUG 0-0: Processing register request, offset 0x1000,
length 1...
[ 29.159696] EtherCAT DEBUG 0-0: Register request successful.
0x00 0
Sometimes the hang is before the register read out is printed, sometime
just after, and some times I get the prompt, and the hang is shortly
after. But not enough so that I have managed to get further information
(yet).
A (perhaps) interesting observation, when doing this as root, the
register read out is (almost) always 0x00 0, whereas when running as
non-priveleged user, the readout is random garbage before the hang. As
non-priveleged user, it is sometimes possible to read the register a
couple of times before the hang occurs.
I therefore strongly suspect that the hang occurs in the EtherCAT-IDLE
thread, or some other kernel thread.

Under preempt kernel the kernel itself has realtime capabilities, so
you can use the generic driver.
I know, I am "using" it. But after starting to use it beyound basic
testing, I now look on a bug report with the mentioned bug report.
Please show the debugging output of the ethercat command if you read
the register.
How do I enable debug output of the ethercat command?
