Comment(by pgf):

 ah ha.  tested with "dmesg -n 5", with this resulting log:

 {{{
 +r[  105.091540] sdhci_reset: wlan w/u control is 0x0
 [  105.096470] sdhci_set_power: new power value = 14
 [  105.111507] sdhci_set_power: new power value = 14
 [  105.163214] sdhci_set_ios: power off for mmc0 from b0671325
 [  105.169105] sdhci_set_power: new power value = 0
 [  105.174005] sdhci_set_power: new power value = 14
 [  105.192073] mmc2: error -123 during resume (card was removed?)

 }}}

 this looks familiar?


 for comparison, a normal resume with that log level set looks like:

 {{{
 +r[   95.191406] sdhci_reset: wlan w/u control is 0x0
 [   95.196333] sdhci_set_power: new power value = 14
