multiple linux panels reboot at the same time (maybe from network traffic)
Hi this is an interesting and challenging question.
We build customized linux boards, using kernel 220.127.116.11.
The boards boots up to linux prompt, not running apps.
Developers have 1 or 2 boards each, doing their own tasks.
The Atmel ARM board has one 10/100 ethernet port, one GIGE port.
We don't find correlations between which interface is used with the reboot issue.
Once a while, we found multiple boards reboot at the same time, (not all of them).
We suspect it's the network traffic caused reboot, as they reboots at the same time.
But when linux reboots, it doesn't display any useful message. It's just like you reset the power, and all you see is the uboot prompt again.
We did use expensive power supply to make sure this is not power glitch, but no difference.
Any suggestions ?
