"mmc_host mmc0: WARNING: IMR=0x00004040" on debug console

Hi,

i updated from kernel 2.6.35.3 (from kernel.org) to kernel 3.2.1 (from 
kernel.org) on arm (at91stamp9G20) and have a MMC card which can be 
completly disabled with a hardware switch. The mmc card is then used by 
another processor without linux. That works very well.
My question is, why i get always the message "mmc_host mmc0: WARNING: 
IMR=0x00004040" after i removed the mmc card slot once. That's a new 
behavior with 3.2.1. I had no message with 2.6.35.3.
When the mmc slot returns to linux, the message stops and i get:

mmc_host mmc0: WARNING: IMR=0x00004040
mmc0: host does not support reading read-only switch. assuming write-enable.
mmc0: new SD card at address b368
mmcblk0: mmc0:b368 H1697 1.91 GiB
  mmcblk0: unknown partition table

That's fine.

Should i just ignore the message (or simple patch 
driver/mmc/host/atmel_mci.c)?

TIA


Tom
