Hello,<br>
<br>
we found out that the problem was in the e1000e driver, which
caused the System to freeze under RTAI.<br>

We tried to use only the e1000e driver for kernel 4.9.80 and no
other patches. Additionaly we tried the e1000e driver <br>
for kernel 3.18.22 with rtai 5.0. The problem remains the same
in both cases.<br>
<br>
There is no output to the syslog when the system freezes.<br>

<p class="MsoNormal"><span>One of the first things you
should try is to triage the patches by rolling them back
and then adding them one at a time and testing until you
find which patch appears to introduce the problem (or
whether it exists in the baseline without any patches).
In most cases you can then try skipping that patch and
applying subsequent ones until you find more problematic
patches or you successfully apply the remainder.</span></p>
