Absolutely no, unless it is reproducible on every boot.
No bnx2 changes between stables and no net/core/ changes.

I personally suspect the pile of ACPI changes that went into 2.6.27.4

There is nothing in the networking bits that could have even remotely
caused this.

Only for your info, it looks like a warning, I posted few days ago. 
But trace path is different. (I use e1000e and have disabled hr-timers). I sent
similar warning with 2.6.26.5 kernel.
