Subject: "mmc_host mmc0: WARNING: IMR=0x00004040" on debug console
Date: Thu, 19 Jan 2012 17:11:44 +0100 [thread overview]
Message-ID: <1326989504.2687.3.camel@salbei.fritz.box> (raw)
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
