Great. This time they seem to match!

Oh, SRP points to useful code now (the line after a jump subroutine call)
but the instruction pointer, IRP, does not point to a location that could
have caused the Oops :(. c0016410 is not preceded by any memory access at
c001640a: 41c2 moveq 1,$r12
c001640c: 649a move.d [$r4],$r9
c001640e: e9c4 lsl.d $r9,$r12
c0016410: 2f2e 0000 0040 add.d 40000000,$r2
c0016416: ed23 lsrq 13,$r2
c0016418: c623 lslq 6,$r2
Explanations could be that the code memory is overwritten or that the oops
somehow is corrupted. What exact kernel version are you using, are you using
the "official" one distributed with the developer board ? If this really
is a bug somewhere it should have been noticed long ago in our own harddisk
products, that is what is troubling me.
