That's odd ... it's behaving like a resource conflict.  However, the
ports and interrupt trace didn't betray anything.  What does lspci -vv
say for each of the devices?  Also, if you remove the sym2 module in the
problem case, does the sungem come back to life?

I'm afraid I can't see anything relevant looking over the sym2 changes,
so you might need to bisect this to identify the culprit.
