Multiple computers getting netio.sys BSOD after 2022.2.1.9 update

We're having an outbreak of DRIVER_IRQL_NOT_LESS_OR_EQUAL BSOD's in driver NETIO.SYS. Netio.sys caused BSOD's are usually tied to network drivers but that doesn't make sense because this started happening all of a sudden on multiple computers. These are fully patched/updated Windows 10 Pro computers. The common thing we're seeing is Sophos was updated to version 2022.2.1.9 around 7/20/22 on all of them. Any insight from Sophos on if the blue screen of death crashes are being caused by the latest version of Sophos?

  • Well, sort of...

    We did file our own case on Monday and are now working through the process with a dedicated support representative.

    At least for our case I can confirm that support won't hand out the patched driver without FIRST getting at least one full memory dump and the SDU logs. "Active memory dump" will be sufficient, though.

    So in the meantime we have set up two of our more heavily affected users with the required settings in order to collect the required type of memory dumps.

    Basically we are "waiting for BSODs" now (the same users totalled 5 BSODs together yesterday... but you know the deal with Murphy...).

    Once I manage to collect and upload them, they will have a look into that - probably to verify if the case is the same one the patched driver is supposed to address.

    Depending on that we'll see how this proceeds...
