Unexpected reboot with firmware 1.13.0

[Schwefelholz]

I've just upgraded to the new firmware and I'm facing following issue:

When using the WebUI CPA's "Run" button or pressing on the S-132 the system just reboots instead of going into RUN state.
Toggling the "Run" switch on the physical CPA is working fine.

Actually, I downgraded to Firmware 1.12.0 again and the behavior of the WebUI CPA and the S-132 is back to normal. Upgrading again to Fw 1.13.0 reinstates the odd behavior.

Hmmm, strange. Seems to be working now...

It was absolutely reproducible, changing from 1.12.0 to 1.13.0 forth and back and forth.
Then I decided to check out the Cromemco firmware and it was working fine.
Then again I installed the IMSAI 1.13.0, and now everything seems to be OK...
