Yes. 11-CURRENT r279090 from the 21st of Feb.

Works fine off the SD card, problems with the eMMC. The ethernet is about 2 x faster than a Pi.

What is the problem with the eMMC?
I can read and write OK, but the 4Mb offset (reserved for the "gadget", I guess) has me confused:
Code:
=> 8192 7544832 mmcsd1 MBR (3.6G)
   8192 61 - free - (31K)
   8253 4095 1 !12 [active] (2.0M)
  12348 4036 - free - (2.0M)
  16384 7528448 2 freebsd (3.6G)
7544832 8192 - free - (4.0M)
Even if gpart(8) is doing the right thing, the copy-to-emmc script can't create the FAT partition:
Code:
+ gpart add -a 63 -b 63 -s 2m -t !12 mmcsd1
mmcsd1s1 added, but partition is not aligned on 4194304 bytes

+ newfs_msdos -L EMMCBOOT -F 12 /dev/mmcsd1s1
newfs_msdos: trim 4095 sectors to adjust to a multiple of 8192
newfs_msdos: meta data exceeds file system size

+ mount_msdosfs /dev/mmcsd1s1 /mnt
mount_msdosfs: /dev/mmcsd1s1: Invalid argument
I have no idea what newfs_msdos(8) is trying to tell me about meta data. Any clues gratefully received. :)

Ian.
