SmartSDR 2.8.1 and BSOD

Have started having BSOD computer reboot after SmartSDR 2.8.1 installation. Computer reboots with a portcls.sys error. This sometimes clears on the re-boot and sometimes not. Once I had to reboot three times in a row to get the system operational again.

This is tied to the DAX program opening.

I see this issue mentioned in the release notes on SSDR 2.8.1 as an issue after 2.6.1 Alpha testing.

Any resolution yet?

    Hi Darryl

    I think I answered this on FaceBook, but if not, it is something that is seen by some customers and some do not see it at all. Not that that helps you at all.

    I've opened a support ticket for you.

    Hey, Mike,

    Thanks for the response here. I don't do Facebook, so would not have seen it there.

    Sounds like a problem that is going to be fun to troubleshoot.

    Thanks for opening the ticket and we'll see where it leads.

    You won't like my answer, but I thought I would share it. It is like using a hammer to fix it. :)

    I had a couple of friends with this issue and I suggested they rebuild their Windows computer from scratch as they were not able to isolate it. They did and the problem went away.

    I raised a support ticket for this and was told it was part of defect G7368 which was still pending, do you know when this is being fixed?

    You are right Mike.

    Not going to re-build the computer to fix this.

    Have you tried running System File Checker? You could have a system file that is causing this problem. Open a command prompt as Administrator and type: sfc /scannow <enter>

    That has fixed odd problems for me in the past.

    Thanks for this insight, James. It found some problems on my system that it fixed. I wasn't having any Flex issues, but I feel better about having things cleaned up.

    I can easily reproduce this 50% of the time by booting up discord right after turning on my pc. If I completely uninstall SmartSDR the issue goes away. There is a issue with Flexs drivers here. Super annoying bug

    As they say, it takes 2 to tango. :)

    You can play your message both ways. If you uninstall Discord do you crash at all? Sadly, it doesn't bring us to the conclusion anyone wants.

    I would uninstall both. Reboot. Install Discord and then install SmartSDR.

    You may also want to open a support ticket so that we can follow up with it further.

    FWIW - for my installation the BSOD issue seems to have either gone away or greatly reduced in frequency. Microsoft update giveth and Microsoft update taketh away?

    Will update if/when things change. For now I'm no longer trying to troubleshoot such an intermittent issue.
