Issue The SafeGuard Enterprise boot stops with a Page Fault message at POA level
Known to apply to the following Sophos product(s) and version(s) SafeGuard Device Encryption
Operating systems All supported Operating Systems
The SafeGuard Enterprise Power on Authentication (POA) is based on FreeBSD. If during the booting up of this micro operating system, it stops with a so-called Null Pointer reference (which means that an error has occurred during the start phase), a 'Page Fault' message is displayed and the system is halted.
Typically the start of the POA stops because the hardware enumeration of the installed internal devices by the FreeBSD encounters an error. To get round this type of issue, use the hot keys integrated in the POA to change the hardware handling during the FreeBSD startup.
To solve a Page Fault at POA level do the following:
The above steps should solve the 'Page Fault' error. However, if the issue still persists then please contact Sophos Technical Support.
