Comment:
2007.2: My 8gb (one large ext3 partition) SD drops the partition every now
and then: sometimes I feel like it has something to do with GPS (like
using tangogps, loading maps from the card, then when I turn the GPS off,
tango can't find the maps anymore -> the /media/card is empty) and
sometimes.. it just drops.
Sometimes I can remount the partition (usually only by rebooting),
sometimes I have to create the partition again with fdisk (but the data is
still there and I can use it).
This is what my dmesg says:

so as you see, it might have also something to do with suspend. Though it
has happened also when the power save features have been turned off.
