[etherlab-users] e1000e driver still not working with 3.2 kernel with latest stable-1.5 branch?

[Jürgen Kunz]

Hello Daniel,

I am using this combination for a while now, with 32- and 64-bit
versions of the 3.2er Debian RT-Kernel. If there is a EtherCAT device
connected to the computer, the driver works fine.
There are two issues in this driver version, if there are no EtherCAT
devices connected. The first, the one you mentioned here, is when the
EtherCAT Master starts up with no device connected, then the
network-adapter is continously reseted until a device is connected. It
may hang the computer if no device is connected for a while.
The second issue is that when the link is plugged off, the link state is
not updated. Unfortunately, I did not have time yet to correct these issues.

Greetings,
Jürgen Kunz
