This is different to Sean's situation, it's FAT format here vs ext3 for
him, and spewing fatal hard errors to communicate with the card, rather
than logical errors in the filesystem.

| failure:
| Buffer I/O error on device mmcblk0p1, logical block 168
| end_request: I/O error, dev mmcblk0, sector 266
| glamo-mci glamo-mci.0: Error after cmd: 0x8020
| glamo-mci glamo-mci.0: Error after cmd: 0x8122
| mmcblk0: error -84 sending read/write command  <=== failed
| end_request: I/O error, dev mmcblk0, sector 97
| FAT: unable to read boot sector
| No suspend/resume involved.

OK.  Well I think it's a different problem somehow.  Maybe try sticking
your thumb on it during this to see if it is a physical connectivity

Also I see it's a spew so maybe this isn't easy, but any log messages
with this kind of format are also interesting

[    2.330000] glamo-mci glamo-mci.0: powered (vdd = 20) clk: 16666kHz
div=2 (req: 16666kHz). Bus width=0

since they tell us the clock rate, voltage we selected and whether we
are in 1 or 4 bit mode.  If you do suspend, you should get a set of them
again in dmesg.
