Would you be able to send the entire dmesg, along with:
The log message are attached to the first message, where I missed to
carbon-copy linux-sgx@ [1].
cat /proc/iomem # (as root)
and
cpuid -1 --raw
I am going to provide that next week. (Side note, Intel might have some
Dell XPS 9370 test machines in some QA lab.)
I'm suspecting either a BIOS problem. Reinette (cc'd) also thought this
might be a case of the SGX initialization getting a bit too far along
when it should have been disabled.
We had some bugs where we didn't stop fast enough after spitting out the
"SGX Launch Control is locked..." errors.
Kind regards,
Paul
