SD card is unwritable after resume from suspend

I'm using suspend on battery for some weeks now. One big issue is, that sometimes (once a day or more often) the SD card is non-writable after resuming from suspend. My /home partition is on the SD card so I need to reboot in order to resolve this issue.

I tried on Sebastian's advice the kernel from !711 but it didn't resolve the problem nor mitigated it.

The kernel log when this happens has entries like this:

If you need more debug information, just let me know how to obtain/collect them.
