BeagleBone SD card problems

[Werner Thie]

Hi all

just got my fingers wet with a Rev A6 Beaglebone. Being a long time user 
of FreeBSD I found of course Tim Kientzle's project on github. Setting 
up a VM and the building of an image was a nobrainer, mahalo and kudos 
to Tim!

When experimentally adding a swap file I encountered the following 
message repeatedly on console:

dd if=/dev/zero of=/usr/swap0 bs=1024k count=512

ti_mmchs0: Error: current cmd NULL, already done?
:

This is coming from the MMC/SD/SDIO, driver in

/usr/local/src/sys/arm/ti/ti_mmchs.c

Is there anybody out there, who can shed some light on this problem and 
push me into the right direction.

This happening with the original 4GB microSD, which works flawlessly 
with the Angstrom Linux image on it originally and also with other cards 
I tried.

Mahalo, Werner

PS:

- After adding swap space the bone is now currently compiling Python27, 
although spewing the above ti_mmchs error mostly when downloading...

- I also timeout errors when compiling sqlite3 (a really big source) 
when the swap was actually used
