I/O errors on NAND on beagle rev C3

Hi folks

I've had problem upgrading my beagleboard C3 for a while; today, I reflashed kernel and initrd, got problems loading the initrd I had written but not the kernel.

Upon boot, I could see the MTDs again (in the past I couldn't anymore due to a missing config), but flash-kernel gives only I/O errors.

Is anybody else seeing I/O errors to NAND with a beagleboard rev C and Linaro OMAP kernels? 2.6.35-1003-linaro-omap is what I have here

I wonder whether it's the hardware being dead, or a kernel bug

Thanks
