This doesn't look good. So the cover detection works. When you close it, tablet tries card detection, but gets command timeout to CMD8 (= SEND_IF_COND command, first or one of first commands, reply should be list of voltages supported by card). Looks like card drops dead and does not respond (in time at least). If the tablet previously came with older OS2007 firmware, try that if you can. If it doesn't help try different kernels - if you have stock one you may try some high-speed ones from http://intr.overt.org/blog/.

Still, the latest OS2007 kernel fixes nasty bug that can kill cards so it is not recommended to write to some power hungry SDHC cards with older kernels but it should be to test card detection. It is possible that slot is dead but it still could be some software issue in linux kernel. Maybe also powering device down and removing battery for some time could help.
