Thanks.  That does appear to be an eMMC partition, which probably 
shouldn't matter, but I replicated the configuration on a 2GB class 4 
uSD card, and an 8GB class 6, and it doesn't work on either one.

llc[77]$ sudo fdisk -lu /dev/sdh

Disk /dev/sdh: 3965 MB, 3965190144 bytes
255 heads, 63 sectors/track, 482 cylinders, total 7744512 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

    Device Boot      Start         End      Blocks   Id  System
/dev/sdh1   *          63       80324       40131    c  W95 FAT32 (LBA)
/dev/sdh2           80325     7743329     3831502+  83  Linux

Anybody got a uSD partition layout that works?  I'm suspecting an issue 
with the heads/sectors/cylinders configuration.

(FWIW: I'm also using u-boot-staging-ti, as that's the default for 
beaglebone on the master branch.)
