I just got an HP Stream 11, model 11-r010nr. It is a cheap (less than 200 dollars) laptop that contains an eMMC device for main storage and a microSD card reader.
There was a forum post about the previous generation of this device: https://forums.freebsd.org/threads/freebsd-hp-stream-11-emmc-not-found-during-install.52544/
There was also a post that alludes to an existing pr (but I can't find it): https://lists.freebsd.org/pipermail/freebsd-questions/2015-November/269073.html
I downloaded the most recent 11.0 snapshot (11.0-CURRENT-amd64-20160127-r294912) and was able to boot to uefi (10.2 was only able to boot in legacy mode), but there isn't a storage device detected.
Attached is the dmesg from 11.0, below is hardware information from Windows; let me know what extra information could help.
disk: (SanDisk SDW32G)
controller: (SD Storage Class Controller)
location path: ACPI(_SB_)#ACPI(PCI0)#ACPI(SDHA)#ACPI(EMMD)
controller: (Intel SD Host Controller)
location path: ACPI(_SB_)#ACPI(PCI0)#ACPI(SDHA)
parent: ACPI\PNP0A08\0 (this is the Root PCI Express Complex in Windows)
Since I suspected the eMMC device didn't work, I was hoping the card reader would work so I could merely install to a microSD card; while I don't have a card laying around, it looks like it isn't detected either based on the dmesg.
cardreader: (Realtek PCIE CardReader)
