<p>Thanks Ted. I appreciate the info and the advice to hold off. I
too have read that some graphic cards can cause lock-up. I'll
leave all alone. I'll upgrade, if anything is now upgradable since
the install is so recent. Still....</p>
<p>Have a great day!<br>

<div class="gmail_default" style="font-size:large">Brian, Yes,
wait on taking action. Try to identify the problem. Also, I
recommend staying clear of EFI partition for now. It is for
compliance with the UEFI standards for hardware and kernel
boot. You can read the Wikipedia.com article. I have had to
adjust the EFI boot order, but only on certain machines. If
you boot and login okay no changes needed. <br>

<div class="gmail_default" style="font-size:large">So, right,
plenty of ram, more swap might be desirable, but seems
unnecessary. I would make it a habit to run and read 'top' on
a regular basis to see what is running and what is using ram.
Virtual memory is not an issue. In top Shift+e changes the
units for ram to make it easier to interpret. Also look at
idle(id) and waiting(wa) percentages. I have found these
interesting and instructive. Even after closing Firefox and
then starting top, I find it takes several seconds to get idle
up to 96% or so. <br>

<div class="gmail_default" style="font-size:large">So, try to
re-create or better identify the series of events that lead to
freezes. Have you read the release notes? Some graphics cards
are a boot up issue, and the new kernel is different from
previous ones. You might roll back if you have an option
during boot, to get to the lowest kernel number. Once in
awhile new kernels leave off support for older parts. or
special graphics cards. Audio and wifi not likely to be the
issue. Keep up and join us at the next NMGLUG if you can.</div>
