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?

  • That would mean creating my own separate support case?
    Up to now we're just "strolling along" the existing cases and the main KB-000044389 advisory.

    Our users have developer machines with 32GB RAM each which makes it kinda difficult to provide full memory dumps - even ignoring all compliancy issues there...

    Does Sophos provide access to the test builds without requiring any other input data? I'd absolutely be willing to test drive that with some key users.
