Subject: SDHCI: Ricoh [1180:e823] unable to mount MMC cards.
Date: Wed, 30 Mar 2011 17:23:24 -0500 [thread overview]
Message-ID: <4D93AD5C.1070308@canonical.com> (raw)
The ricoh SD/MMC card reader [1180:e823] is able to read SD cards, I
recently submitted a patch to enable this card reader
(https://lkml.org/lkml/2011/2/11/309).
But it is not able to mount MMC cards.
When I insert an MMC card I get:
mmc0: error -110 whilst initialising MMC card
I traced it down to ETIMEDOUT coming from sdhci_cmd_irq() can someone
give me a clue as to where I should start looking?
