I am seeing some very erratic memory corruption issues all morning,
both with NFS and MMC cards. The traces are at the end of this email.
I have narrowed down the issue to one of the 13 Sakoman patches:
file://sakoman/0001-mmc-don-t-display-single-block-read-console-messages.patch
\
file://sakoman/0002-omap-Change-omap_device-activate-dectivate-latency-m.patch
\
file://sakoman/0003-OMAP-DSS2-add-bootarg-for-selecting-svideo-or-compos.patch
\
file://sakoman/0004-mtd-nand-Eliminate-noisey-uncorrectable-error-messag.patch
\
file://sakoman/0005-video-add-timings-for-hd720.patch \
file://sakoman/0006-drivers-net-smsc911x-return-ENODEV-if-device-is-not-.patch
\
file://sakoman/0007-drivers-input-touchscreen-ads7846-return-ENODEV-if-d.patch
\
file://sakoman/0008-Revert-omap2_mcspi-Flush-posted-writes.patch \
file://sakoman/0009-rtc-twl-Switch-to-using-threaded-irq.patch \
file://sakoman/0010-rtc-twl-add-support-for-backup-battery-recharge.patch
\
file://sakoman/0011-soc-codecs-Enable-audio-capture-by-default-for-twl40.patch
\
file://sakoman/0012-soc-codecs-twl4030-Turn-on-mic-bias-by-default.patch
\
file://sakoman/0013-omap-mmc-twl4030-move-clock-input-selection-prior-to.patch
\
Not applying any of them makes the corruptions go away.

Any comments?
