Description Henrik Hudson 2018-05-30 21:57:54 UTC
Since updating my poudriere build box on AWS EC2 from 11.1-p6 to -p9 and -p10 some of my builds have been failing in random spots (p-state errors, seg faults, etc...) Specifically, lang/go and lang/rust . 

If I freebsd-update rollback to -p6, reboot, and run the build for lang/go it works without issue.

I also have a physical box that does builds and it's working fine on -p10 for the same ports.

I put a lot of build output and errors in this thread:

This is the host OS I'm rolling back. My poudriere jail is either -p10 or 11.1-RELEASE .
Comment 2 Colin Percival freebsd_committer freebsd_triage 2018-05-31 18:27:19 UTC
This is caused by a bug in the Spectre/Meltdown patches (FreeBSD 11.1-RELEASE-p8).  There is a fix (https://lists.freebsd.org/pipermail/svn-src-all/2018-May/163829.html) but it hasn't been merged to the release yet.

We should be getting an Errata Notice to fix this in the release soon.

Good deal. Thanks.
Comment 4 Henrik Hudson 2018-06-26 04:26:43 UTC
Did this fix make it into 11.2-RELEASE? or will there be an Errata and fix notice after release?
Comment 5 Colin Percival freebsd_committer freebsd_triage 2018-06-26 04:45:30 UTC
This was fixed in releng/11.1 a few days ago as https://security.freebsd.org/advisories/FreeBSD-EN-18:07.pmap.asc and was fixed in stable/11 way back around 11.2-BETA2.

So everything should be fine now as long.

Thanks. Sorry, missed the Errata announcement.
