I have had reports of systems rebooting for no apparent reason. These systems never showed this issue until they were 
wiped and loaded with QNX. Current version they are running is 6.3.2a.

This design uses AMI BIOS with A20 Gate set to Fast. 

Does anyone know if 6.3.2a still uses the x86_enable_a20() function? If so, is it being used by one of the OS subsystems
? All I can think of is that this is being used by the OS and port 0x92 on this hardware platform does not handle it 
well.

The issue has only occured three times (at least that is all that has been reported) over the last two years. I am 
concerned as we prepare to move all deployments to QNX.
