Are  you  absolutely  sure  that  your  SDRAM  has  been  initialized
correctly?

This looks somewhat corrupted to me.

I speculate that your RAM fails in burst mode.  Try  disabling  burst
mode  (set BI bit in memory controller) and/or caches in Linux; if it
starts to work then you know where to look after.

Best regards,
