The FreeBSD Release Engineering Team is pleased to announce
availability of FreeBSD 10.4-RELEASE. This is the fifth
release of the stable/10 branch, building upon the stability
and reliability of 10.3-RELEASE and introducing new
features. Some of the highlights: 10.4-RELEASE is the first
FreeBSD release to feature full support for eMMC storage,
including eMMC partitions, TRIM and bus speed modes up to
HS400. Please note, though, that availability of especially
the DDR52, HS200 and HS400 modes requires support in the
actual sdhci(4) front-end as well as by the hardware used.
Also note, that the SDHCI controller part of Intel Apollo
Lake chipsets is affected by several severe silicon bugs.
Apparently, it depends on the particular Apollo Lake
platform whether the workarounds in place so far are
sufficient to avoid timeouts on attaching sdhci(4) there.
Also in case a GPT disk label is used, the fsck_ffs(8)
utility now is able to find alternate superblocks. The
aesni(4) driver now no longer shares a single FPU context
across multiple sessions in multiple threads, addressing
problems seen when employing aesni(4) for accelerating
ipsec(4). Support for the Kaby Lake generation of Intel
i219(4)/ i219(5) devices has been added to the em(4)
