mxs-mmc errors

[BillRandle]

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?

I use i.MX280 with SDIO-connectd WiFi module on our own product (silex SX-570). I see this "mxs_reset_block timeout" message almost every time on bootup. Sometimes only once, sometimes repeating 5-6 times. It seems harmless...I never experienced my SDIO WiFi caused malfunction because of this.

I guess the reset timeout message is not actually error but just information, showing SD driver is tyring to sync up with SD module, but have to track down the source code to make sure.
