As I keep this machine up-to-date with the Ubuntu repositories (it's running Lucid) it's still possible that this is due to improved software stability rather than my use of different physical ports.

I have tried with 4 different 12v high quality power supplies of 2A, 5A, 6.6A and 8.5A. I have also tried 2 different types of wifi cards: Atheros AR5008 and Broadcom BCM4318. They crash while being idle. I don't think its the VIA ethernet driver problem because I have also hit this one and it only happens under heavy network usage, my crashes happen even without any kind of activity. If I remove the wifi cards they all work perfectly fine. The CPU temperature reported by lm_sensors is around 60 celsius. The wifi chipset is really hot to the touch, so my theory is that maybe the wifi card is not responding anymore and this hangs the whole system. Any ideas? Alan This sounds to be an issue with the powersuply on the 5501. The external supply gives you 12V but that it switched down to 3.3V etc on the 5501. Maybe that onboard switch is overloaded because of your wifi board. Soren, what do you think about this? What do you think causes this problem? How can I solve it?

Mike, I can report that I have about 14 power supplies with the label SMP Technologies Inc. which have failed over the course of the last year. I believe this about 80-90% of a set of 5501. Same location but different power sources. The drill usually is: monitoring tools make me aware a host being down, I try the console with no luck. When I power cycle it the red led stays on. Replacing the ac adapter fixes it. My 2 cents.

Our experience is that 9 out of 10 times issues with stability is either problems with the power supply or with the software, especially Linux as it seems to have taken long time for a stable VT6105M Linux driver to show up If it's one of the very few instances where it's a hardware issue just contact r...@soekris.com to request service, if under warranty it will be replaced or repaired at no charge. But try another power supply first, I will do that when i have the right connector (Friday maybe). and if running Linux, ensure you have the stable drivers. i'm using debian gnu/linux 5.0.5 and, now, the box don't crash for 4days and half :) signature.asc Description: Ceci est une partie de message numériquement signée ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

Libsensors under openwrt shows 50-55 C for net5501-70, 43-48 C for Alix 2D13 (both with closed box), but this result must taken with grain of salt because Alix sensor is not calibrated (don't know about Soekris). Yes, the net5501 use more power than an Alix 2D13, and it should considered the the second bank of memory, the additional ethernet controller, the multi-io controller, the SATA bridge, the more complex power supply to support PCI expansion But remember that the Geode LX CPU is specified to operate with a case temperature of 85 degrees censius, so a die temperature of 55 degrees censius or even 70 degress is no problem at all by itself.
