Thank you (once again) for your helpful answers, Jason! After having done some more experimenting following your suggestions, I've found that increasing the deadlock threshold (by several orders of magnitude) does not make the problem go away, nor does only increasing the number of memory channels to 4. Nonetheless I suspect your gut feeling that bandwidth problems are to be blamed still holds, as increasing the DRAM size to 8192MB makes the "deadlock" go away and is accompanied by the following message:
> warn: Physical memory size specified is 8192MB which is greater than 3GB. > *Twice the number of memory controllers would be created.* More memory controllers => less congestion in the memory controller(s) – makes sense to me! I wonder if the underlying issue has more to do with the cache hierarchy of my system (e.g. no L2 cache, only small L1's) than the protocol itself. Either way, having found a band-aid solution is good enough for my current purposes :) Thanks again for your help Jason!
