SanDisk MMC card timeouts

Hi,

We're seeing MMC timeout errors with SanDisk MMC cards and a 2.6.32
kernel (BeagleBoard Rev C5).

The suggested fix of setting dto timeout to 14
(http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42214.html)
doesn't help. Any other suggestions with any familiar with this issue?

The errors seem to be entering logs from mmc_blk_issue_rw_rq in
drivers/mmc/card/block.c
Here is a boot log:

Does the same happen with a more recent, e.g. 2.6.39 kernel?
