Hmm. Care to verify that your onenand really gets detected at 83 MHz like
your earlier logs show? Below is a patch that should show it.
before the corruption appeared, I looked a couple of times in syslog and
the freq there was 83MHz. Including after I disabled CONFIG_OMAP_GPMC_DEBUG.
Also, do things now work reliably for you with CONFIG_OMAP_GPMC_DEBUG
enabled? Or does that also produce corruption after few reboots?
CONFIG_OMAP_GPMC_DEBUG is disabled, shall I enable it?

Where am I supposed to get the output from ^^^ if rootfs become
corrupted? The problem appears after poweroff/restart when it is already
too late to get the syslog.
BTW, did you compare all the GPMC registers with and without
HWMOD_INIT_NO_RESET?
