A few weeks ago I posted a problem I was having with my machine rebooting whenever I wrote to an md array (details below). The problem turned out to be using the SiI 3132 2-port SATA card in the PCIe x16 slot of the ga-ma74gm-s2 motherboard. I contacted Gigabyte and they said that the x16 slot is designed for *video only*. So just a heads-up if you plan to use this board for a low-power file server. -Matt On Mon, Feb 02, 2009 at 10:14:50PM -0600, Matt Garman wrote: > > I have two four disk raid5 arrays on Ubuntu Linux 8.04 (AMD64). > Both are using XFS for the filesystem. > > $ uname -a > Linux septictank 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC > 2008 x86_64 GNU/Linux > > I recently replaced the motherboard and processor: switched from an > Intel Q35 motherboard + E5200 CPU to a Gigabyte GA-MA74GM-S2 > motherboard (AMD 740G/SB700) with an 4850e CPU. > > I ran a ton of benchmarks under the old configuration, and intend to > do the same with the new hardware.
