North Bridge Disconnect?
by Thomas Dineen
Gentle People:
I am developing an optimization application that uses the CPU quite
intensely
for long periods of time on a CentOS 6.9 machine. Some test runs can
run for hours or even days.
On a particular test the the OS crashes to a black screen with the
message "North Bridge Disconnected"
printed in the upper left.
The application is carefully designed to not simply consume too much
memory and run out, and observation
of the System Monitor confirms this.
What could be the cause? Is this a bug in my code, quite possible
given the fact that I an still testing and debugging?
Can a bug in a user application get into Kernel space and crash the machine?
Or is it likely a hardware problem on the Motherboard?

Audacity: "Error opening recording device"
by Matti Pulkkinen
Hello,
I'm trying to use Audacity to record the line in on my PC, but I always
get the following error:
Error opening recording device.
Error code: -9997 Invalid sample rate
Sounds like an easy-to-fix problem, but the same thing happens
regardless of what sample rate I choose. Checking with "pacmd
list-sinks" I found that the sample rate for my card is 44100 Hz, so
that's what I'm trying to use now that I've checked all possible sample
rate options Audacity offers. Also, Audacity offers a bunch of different
recording devices with names along the lines of "HDA Intel PCH: ALC892
Alt Analog (hw:0,2): Front Mic:0" but the same error happens with all of
them too.
Based on what I could find online, it seems like people have had this
issue mostly on Windows, and then it was to do with either not having
updated drivers or having set the device's sample rate incorrectly. Has
anyone here run into something like this before on Fedora? Any ideas
where to start trying to fix this?
