On a Lenovo Thinkpad x220 and kernel 3.7.1-2.fc18.x86_64 (although this has been an issue for a while from memory) after a period of uptime with suspend / resume although I'm not sure if it ultimately makes a difference I get the following errors in dmesg and any SD cards aren't seen.

[80060.019176] mmcblk0: error -110 sending status command, retrying
[80060.019206] mmcblk0: error -110 sending status command, retrying
[80060.019236] mmcblk0: error -110 sending status command, aborting

I usually just reboot to fix the problem but to try and get around that I removed the modules and modprobed them again to try and reset the driver/hw

rmmod sdhci_pci; rmmod sdhci; rmmod mmc_block; rmmod mmc_core
modprobe sdhci_pci

Then reinserted and got the following crash
