It's likely that one of the hardware watchdogs is running and nothing
is feeding it, leading to a SoC reset.

It's unusual that there's not other output interleaved here, which
suggests u-boot is getting stuck somewhere it shouldn't?

Can you capture the entire console output from BMC reset to the
occurrence of this condition, and then send it in reply here?

Some other details would help:

 * What platform are you testing on?
 * What's the upstream commit of openbmc/openbmc that you're testing?
