opteron 170, part 4

[ link: opteron-170-p4 | tags: hardware opteron | updated: Thu, 10 Aug 2006 21:15:33 ]

I am getting sick of this. It froze again.

So to date I have disabled swapped out the motherboard (but still have the same NForce4 chipset), enabled all sorts of debug features in the kernek, removed the Nforce4 network card (based on a hint on a web forum), and put in a PCI NIC. It's still unstable.

I had noticed that it never froze under console, just under X. The next attempt is to disable DRM. I did this through the xorg.conf... let's see what happens next. I am no longer optimistic.

Update

Not being optimistic pays off. I've been running my Opteron 170 stable w/o DRM for almost a week.

opteron 170, part 3

[ link: opteron-170-p3 | tags: hardware opteron | updated: Sat, 05 Aug 2006 13:15:55 ]

Over the last few days, I have been experiencing odd crashes. I have been able to narrow it down to network activity. Most of the time this has been triggered with NFS access; I assume that it has something to do with large UDP fragments; my MTU is 1500.

The last couple of days I have had a serial console connected to the machine, and my laptop standing by waiting for another crash. It occurred, but something really bad happened because on the console I only got:

[   65.597418] [drm] writeback test succeeded in 1 usecs
[  835.777136]
[  835.777138] HARDWARE ER

... and then the system was completely locked up. I really wish I knew what that HARDWARE ERROR was :(

I guess this sounds familiar. On day one, I was looking for answers and found a windows user having the same problems. I have ordered an e1000 NIC.

I put an old 3COM NIC into a PCI slot and have been using that.

Yesterday, I wrote about how my Opteron 170 was crashing at random times. Today I have a working system.

[ link: opteron-170 | tags: hardware opteron | updated: Thu, 03 Aug 2006 23:32:14 ]

My new shiny Opteron 170 just came in. I used to say that Opteron 1xx line was a waste of money because it was basically the Athlon64 but more expensive because of the Opteron branding. Recently AMD made the choice easier by dropping dual-core Athlon64 processors with 2M of L2 cache. The last line of Athlon64 S939 will have a 512k L2 cache. That's a mere 256k per core. And isn't that only twice the size of the L1 cache? yuck!

So, I blew the extra $300 on the extra 1.5M of L2 cache.
