I can't speak for Netgate directly on this, I wasn't involved in that decision. Personally I prefer Intel because you're not paying for features that pfSense can't use. Both in money and power consumption/heat. In FreeNAS that's different. I imagine they might well use the TCP offloading the Chelsio NICs offer. Though I've never looked into it. More cooling never hurts! Steve

Try these. I can't test them against hardware but they load fine in 2.5.2: [2.5.2-RELEASE][admin@252dev.stevew.lan]/boot/modules: ls bwi_v3_ucode.ko if_wg.ko linker.hints t4_tom.ko toecore.ko [2.5.2-RELEASE][admin@252dev.stevew.lan]/boot/modules: kldload t4_tom.ko [2.5.2-RELEASE][admin@252dev.stevew.lan]/boot/modules: kldstat Id Refs Address Size Name 1 15 0xffffffff80200000 3aea720 kernel 2 1 0xffffffff83f19000 1000 cpuctl.ko 3 1 0xffffffff83f1a000 2698 intpm.ko 4 1 0xffffffff83f1d000 b40 smbus.ko 5 1 0xffffffff83f1e000 344d8 if_wg.ko 6 1 0xffffffff83f53000 137b0 t4_tom.ko 7 1 0xffffffff83f67000 c7e toecore.ko t4_tom.ko.txt toecore.ko.txt Remove the .txt extension.
