We had some bugs where we didn't stop fast enough after spitting out the
"SGX Launch Control is locked..." errors.
Let’s hope it’s something known to you.
Thanks for the extra debug info. Unfortunately, nothing is really
sticking out as an obvious problem.
The EREMOVE return codes would be interesting to know, as well as an
idea what the physical addresses are that fail and the _counts_ of how
many pages get sanitized versus fail.
Is there a knob to print out this information? Or way to get this
information using ftrace? I’d like to avoid rebuilding the Linux kernel.
But, I don't really have a theory about what could be going on yet.
Kind regards,
Paul
