Subject: MMC read errors
Date: Thu, 01 Mar 2012 12:57:34 -0800 [thread overview]
Message-ID: <4F4FE2BE.70402@irobot.com> (raw)
I'm seeing weird read errors on a DM3730. Has anyone seen anything like
this before?
Environment:
factory images from
http://cumulus.gumstix.org/images/angstrom/factory/2011-08-30-1058/
loaded onto and MMC card on a
Gumstix WaterStorm on a Chestnut board
Commands:
dd if=/dev/urandom of=garbage bs=1024 count=1048576
while true; do md5sum garbage; done
example output:
99e983a8f17f3258ddaff73bf622db47 garbage
99e983a8f17f3258ddaff73bf622db47 garbage

dmesg has nothing interesting.
Any clues?

Although I've also seen similar behavior on a recent 3.2 kernel using
oe-core.
