--2tWkrNKppd65XSnD Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I've recently acquired an AMD64 box (dual Opteron 242, SiS Master@-FAR motherboard (http://www.msi.com.tw/program/products/server/svr/pro_svr_detail.php?UID= =3D484). See below for more details). I find it very unstable running with 8 GB memory, though 4 GB are not a problem. At first I thought it was the onboard peripherals, but after disabling them it still persisted. What's unstable? I only once got it through the boot process. Running a 5.3-RELEASE i386 kernel it panics, though I haven't investigated the panic (yet), since I'm not interested in the i386 kernel. The amd64 5.4-PRERELEASE kernel just hangs/freezes. When the peripherals are enabled, it's after probing the onboard NIC (bge) and before probing SATA (no drives present). I've done a verbose boot, of course, but no additional information is present. The NIC is recognized, and that's all. Without the peripherals, but with a 3Com 3c905 PCI NIC, it continues beyond this point, but doesn't enable the NIC. I don't have dmesg output for these attempts, so I can't produce the exact message, and I suspect it's not important. It continues until trying to mount NFS file systems, where it hangs for obvious reasons. Pressing ^C causes the system to either panic (and be unable to dump because I don't have that much swap) or just hang. None of these problems occur when I use 4 GB memory. About the only strangeness, which seems to come from the BIOS, is that it recognizes only 3.5 GB. If I put all DIMMS in, it recognizes the full 8 GB memory. I realize that this isn't enough to diagnose the problem. The reason for this message now is to ask: 1. Has anybody else seen this problem? 2. Has anybody else used this hardware configuration and *not* seen this problem? 3. Where should I look next? I'm attaching the (non-verbose) dmesg from a successful boot.
