SDHCI I/O errors

I have an SDHC card that works fine in a camera and in several
different USB-based readers.  On my sdhci reader (the integrated one
on a Lenovo X220), though, it spews stuff like:

[  306.103556] mmcblk0: error -110 sending read/write command,
response 0x0, card status 0x400b00
[  306.103559] end_request: I/O error, dev mmcblk0, sector 410272
[  306.103595] mmc0: Got data interrupt 0x00600000 even though no data
operation was in progress.
[  306.103597] sdhci: =========== REGISTER DUMP (mmc0)===========

all over the logs and fails some (but not all) attempts to read it.
The startup messages are:

[1180:e823] (rev 4)
