mxs-mmc errors

We are sometimes seeing errors like this on power up:

  mxs-mmc: MXS SSP Controller MMC Interface driver

  __mxs_reset_block(f0010000): timeout when resetting

  __mxs_reset_block(f0010000): timeout when resetting

  __mxs_reset_block(f0010000): timeout when resetting

  __mxs_reset_block(f0010000): timeout when resetting

  __mxs_reset_block(f0010000): timeout when resetting

  __mxs_reset_block(f0010000): timeout when resetting

  mxs-mmc mxs-mmc.0: mmc0: MXS SSP MMC DMAIRQ 82 ERRIRQ 96

 

This is on a MX287 board with onboard eMMC chip. The problem is intermittent and will usually go away on the next reboot. Kernel version is 2.6.35.

 

Has anyone seen this before or have any ideas? Hardware problem (noise, power) or driver problem?
