Are you using the "rescue" image supplied with the kernel?
If not - there is a buf in the ptable code that I think could cause

Is the "NICE_DOGGY" watchdog kernel config option disabled?

Do you have the "SDRAM clock fix" on your board?
(The problem is described on this list before I think - when resetting
the SDRAM clock from ETRAX goes away, but the SDRAM might not be finished
thus still drives the bus)
