North Bridge Disconnect?
by Thomas Dineen 02 Jul '20

02 Jul '20

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? Thomas Dineen

Audacity: "Error opening recording device"
by Matti Pulkkinen 01 Jul '20

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? -- Terveisin / Regards, Matti Pulkkinen
