No ethernet interface found after suspend-resume

Fri Apr 30 04:06:26 EDT 2010

Hi,
 The curious thing is - After the SDIO card has been detected.
  If i reset the WLAN chip before i do a suspend-resume. Everytime the
sdio card is detected
  during resume. tested with/without Firmware.

  Does this mean to say - Once the card has been detected.
  Can i Keep calling cmd0, CMD8, CMD5.... again and again?

  Am i supposed to send some re-init command to the card during suspend?

Regards,
sriram
