I have been looking at this today together with Ian Campbell at the
mini Debconf-UK. Commit c9cd02c cleans up the uboot syscall interface,
but unfortunately it also corrupts the stack for va_arg passing.
It is only evident when passing a sufficient number of arguments, which
I think is only triggered by the disk accesses.

Patch attached, verified on Ian's qemu vexpress, which he may be posting
some updates on later.
