hello list... PLEASE HELP!!! I would greatly appreciate any experienced recommendation for choosing a motherboard for optimal 6.0-rc1 usage. I need to buy a motherboard (tomorrow...as I've been researching for 2 weeks and my head is spinning from reading maillists). I need a motherboard which is supported well by freeBSD 6-rc1 drivers in regards to SMP and ethernet (including polling..extremely important!!). I have been reading on performance issues with various ethernet controllers and find lots of problems popping up (throughput and polling with SMP kernels). For example, this thread from freebsd-performance shows the em driver is trouble and SMP is not supported for polling (2004 posting in regards to freeBSD 5.3). http://unix.derkeiler.com/Mailing-Lists/FreeBSD/performance/2004-10/0016.html The page http://www.freebsd.org/releases/5.4R/hardware-i386.html doesn't give me the info I need to make decisions and I'm in China so I cannot order a preconfiged product from freebsdsystems. One such board I'm looking into is the Tyan Thunder i7520 (S5360). Everything looks right except for confirming the em driver usage for polling on an SMP kernel. Any experience here? regards,, ke han
