I'm not driver's expert, but maybe you could try some of these: - since 'the list' seems to be busy now, opening a bug report at bugzilla.kernel.org (copy most of these information and lspci -vvv) looks like the best way to not forget about this, - I'd a look at the code and it seems it uses quite coarse locking, so it could be SMP unfriendly by design...; could you try with kernel boot parameter: noirqbalance (or read about SMP issues e.g. for another card Documentation/networking/cxgb.txt).
