Carbon Black Causing Blue Screen of Death
by Artie Kaye

Some users of Carbon Black by VMware have been facing difficulties booting their systems after a recent update.  The problem arises from updated security rulesets, which prevent certain devices from authenticating properly on boot.  This presents as continuous BSoD’s some with the error code of PFN_LIST_CORRUPT.  The company has since rolled back this back and is still working with customers still affected.  It is unknown as of right now what is causing the failure.  The recommended work around is to place affected sensors into bypass mode using the programs console to allow the device to reboot properly to remove the updated ruleset.  If this does not work, rebooting the device in safe mode until it functions is the next step.  The company’s information regarding this can be found in the link below.
