With my 8G Sandisk SD card, i can reliably fix the problems i have been
having by turning on the SD clock all the time. To do this type the
echo 1 > /sys/module/glamo_mci/parameters/sd_idleclk
then do something that will access the SD card before doing a suspend.
This of course won't do the GPS much good, but i think the real fix
might be to give the SD card more clock cycles before and after commands
to give it time to finish executing commands.
