This issue seems to be related to one problem that we have always had.
We can't configure buffers of SMCs, SCCs, etc, to be in SDRAM, because
the processor hangs. We always have to configure buffers in DPRAM. In
other drivers this has not been a problem, because the buffer size is
not very large, so we can allocate it in DPRAM, but for this one, the
buffer size is 0x8000 (32Kb) which exceeds DPRAM size.
Has anybody had the same problem? Can it be an USB specific problem or a
general one?
Make sure that BCR[PLDP] is not set, as per erratum SIU18.
