It depends on whether the hardware is causing the crash on uncorrectable
error to prevent data corruption or the error handler is calling panic()
or somesuch. If it is the former, then you need to disable that feature
- if at all possible (no clue what that platform does).
If it is the latter, you can comment out the panic() for testing
purposes only and inject then. For an example what x86 does, see
"tolerant" here:
