Stack dump on resume - GTA01 - what now?

[Mike (mwester)]

The patch that added the stack dump on suspended transfers works -- see
the dmesg excerpt below.

I presume that this was added to facilitate fixing the situation that
got us into this state to begin with (resume ordering?)... or do I
misunderstand something?

Any pointers on how might I go about resolving this?

Thanks,
Mike
