I don't think a firmware upgrade will make any difference. I believe it's a hardware issue.
My Petrel displayed identical behavior repeatedly, and different AA batteries didn't fix it. I finally switched to a SAFTT battery and the problem disappeared. The Petrel battery compartment spring appears to be a little weak, and from time to time when it compresses a AA battery will lose connection, resetting the computer. The SAFT hasn't displayed this behavior yet, and it's been 15 hours of dive time since I changed it.

Interesting. I wonder if it IS a battery manufacturer issue. I know on my C8 "C" cell flashlight I can only use Duracell batteries. Any other brand and the light will not work. In investigating the issue, the end caps of the different brand batteries are different than the Duracell batteries. That difference prevents contact from being made and as such the light will not work.
So maybe the end caps on some other brand batteries are different than the Saft batteries? And causing a connection issue? B.
