Hi,

I'm working making a ram-boot for an embedded Linux system. I'm having some issues when it boots up. Udev appears to be causing some errors. I've inserted debug messages into /etc/S03udev to find the problematic line, and it appears that this line is causing problems.

/sbin/udevadm trigger --verbose

Seems to be some sort of memory or module problem?? failure is someone sporadic but I've narrowed it down with the 'sleep' statements in /etc/S03udev. They help it fail more consistently in the same location.

Any ideas about what is going on?

What other information would be helpful to diagnose the problem?

Best,

Anthony


The attachment isn't working, so I'll just put the s03udev and log here.
