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.<o:p></o:p></span></p>

<br>
we are <span class="hiddenspellerror">experiencing</span> the same problem with <span class="hiddenspellerror">
rtai</span> 5.1 kernel 4.9.80 and <span class="hiddenspellerror">rtai</span> 5.0 kernel.<br>
The system freezes randomly after several minutes with the e1000e and the <span class="hiddenspellerror">
unofficial</span> patches.<br>
Does somebody have an <span class="hiddenspellerror">idea</span> how to <span class="hiddenspellerror">
