Um, what's after that?  Try "-dddt" and don't let it daemonize.  Lets
get some real logs out of the thing.  Also, what SDHC does your platform
have, and does the SDHC generally suck?  I've used the 2.6.31 libertas
driver with SD8686 and a "Ricoh Co Ltd R5C822" with lots of success.  It
seems to be only with the shadier embedded platform controllers that
either don't support multi-block transfers, or have DMA bugs, or have
other errata that people start having problems.  A lot of that depends
on the quality of your platform's SDHC driver.
