BSOD MACC 8.3.5 Install

[WandaKoz]

Systems Blue Screen during the recent upgrade to MACC 8.3.5. "Unexpected Kernel Mode Trap" stop errors which reference mfeaack.sys.  Is
there a compatibility issue with ENS 10.7 Feb Update and the latest MACC client?

Hi @WandaKoz 

If possible, please open a Service Request with our Support team and we can investigate this further.  Please capture a COMPLETE memory dump and MER file from the affected system.

I am having the same issue. MAC 8.3.5 and ENS Feb 2022 update.

Is there a fix yet?

I am going to try to remove MACC in safemode if I can get the system to stay online long enough.

We opened a ticket with Trellix and the tested version they provided for us did fix the issue. I imagine the fix will be in the next update. 

We will remain on 8.3.4 until the next release to avoid BSOD

Hope this helps.

I ended up having to remove 8.3.5 and I am installing 8.3.4 in the meantime.

What did McAfee/Trellix support give you as a fix? Is it just related to the product version itself or is there a compatibility issue with other product versions installed.

Thanks.

Hello @kblowe 

Its just related to a product version 8.3.5.McAfee/Trellix has planned to release an hotfix(8.3.6) in August 2022 for the reported issue.
