Hi everyone,

My development board has two memory banks, SDRAM (128MB) and PSRAM (16MB).
I've got the linux kernel booting from only the PSRAM, but I can't get a
USB Flash Drive to work properly. It is being detected, but I get the
following messages:
---------------------------------------------------------------
usb 1-1: reset high speed USB device using fsl-ehci and address 4
sd 2:0:0:0: [sda] Result: hostbyte=0x05 driverbyte=0x00
end_request: I/O error, dev sda, sector 0
Buffer I/O error on device sda, logical block 0
---------------------------------------------------------------

This ONLY occurs when I use the PSRAM on the board. I've made no changes
to the drivers and my changes to kernel source were minimal. I only changed
the following (zreladdr, param_phys-y, PHYS_OFFSET).

I'm at a complete loss on how to fix this but it's critical for me to use
PSRAM. Any help is greatly appreciated.

Thanks!
