I've grabbed a few Oops messages (transcribed from photographs, I have the slightly blurry photos to go with the attached text files if needed). The kernel was built from the actual commit point mentioned in the original post. I can provide the kernel binary if needed for disassembly. The crashes all seem to be while the devfs process is running. One thing strange I noticed is that I'm using Gentoo's "OpenRC" boot system, but the crashes only occur when it is configured to start services in parallel (rc_parallel="YES" in /etc/rc.conf). -- -=( Ian Abbott @ MEV Ltd.
