Description (partial)

Following SPA bus error and Jacket watchdog reset will be watched on jacket card crashinfo:

SPI FPGA: TIB SPA1 Bus Error [1/16]
Machine Check Error, can be ECC or Watchdog..

ECC 1 bit errors since last time we cleared = 0 

ECC 1 bit errors while up (total) = 0 

When WBCMTS SPA power is shutdown if power supply violation is watched by power management hardware to protect components on SPA. This error message and SPA crash can be reproduced by using debug image, or debug command on jacket console. We suspect some of filed cases may be caused by this issue too.
