Hi, Between the 14 Feb., 2012 Angstrom image with kernel 2.6.5+, and image 2.6.15 of 1 May, 2012, usb drives (whether flash or actual hard drives) are no longer recognized on the beaglebone rev. A5 That is, the drives no longer show up in /proc/partitions.
Here are the logs and partition table dumps: ################################################ ## BROKEN: kernel 2.6.15 root@beaglebone:~# dmesg ...
