Comment 40 for bug 568711

ok, i did some more test:

- sd-card mounted, formatted in ext4: did not work.
- sd-card mounted, formatted in FAT: did not work.
- any sd-card in the slot, but not mounted: works fine.
- USB-stick mounted, formated in FAT: works fine.
- external harddrive mounted, formatted in FAT: works fine.

so it seems that not ext3 or kjournald is the problem, but mounted sd-cards.

when i put an sd-card in the slot, dmesg gives me:

[ 288.233032] mmc0: new high speed SDHC card at address b368
[ 288.239856] mmcblk0: mmc0:b368 NCard 7.54 GiB
[ 288.239960] mmcblk0: p1
[ 288.405199] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode

so one of these mmc* seems to puts the system in a state that makes suspend fail.
