Additionaly we tried the e1000e driver <br>

in both cases.<br>

There is no output to the syslog when the system freezes.<br>

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