I presumed a fix for something this old but some forums showed a persistent issue.

Just that you weren't actively using the network? If you suspect the NIC, you could try unloading the kernel module, 'lsmod -k' will show you what module is in use. But if this happens when you try to play a DVD, I wouldn't really suspect the NIC unless I had some indication it was involved. Have you installed the Realtek firmware package?</pre> </blockquote> I unplugged and "disconnected" from task bar. Just stopped network traffic. Will unload kernel module in the battery test if necessary. <blockquote cite="mid:20150904085840.52cebc5a@odin" type="cite"> <pre wrap=""> </pre> <blockquote type="cite"> <pre wrap="">Loaded MATE system log and psensor early on to monitor. Logs, as mentioned show no errors; so I presume the crash does not give the system time to register. psensor was showing over heating (no air conditioning here) and processors were set for "performance". I reset the processors for "powersave" and have had normal temps and still am freezing up. This dismissed the overheating theory. I have no way to monitor GPU temperatures but given the freezes are random in time, i.e. 5 min to 2 hrs. I have put this at a "not likely" status. </pre> </blockquote> <pre wrap=""> Are you saying the freezes are random, or happening when you play a DVD?</pre> </blockquote> Random, see above. <blockquote cite="mid:20150904085840.52cebc5a@odin" type="cite"> <pre wrap=""> </pre> <blockquote type="cite"> <pre wrap="">Status: waiting while I push the system with compositor turned OFF.

There is information on the Ubuntu wiki on how to do this if you don't know how, start here: <a class="moz-txt-link-freetext" href="https://wiki.ubuntu.com/Kernel/">https://wiki.ubuntu.com/Kernel/</a> Also, file a bug. It's the only way to get it fixed (if it isn't already in a newer release), but you need to be very clear on how and when it happens. Petter </pre> </blockquote> Sounds good, I will look into a new kernel. I reserved a bug report until I could isolate issue, esp. since no log errors were giving any help. So far the compositor fix seems to be working. On third video and still no freeze. Thank you Petter for the input, helpful. <blockquote cite="mid:20150904085840.52cebc5a@odin" type="cite"> <pre wrap=""> </pre> <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
