Motherboard is a Tyan TigerMP with ECC registered RAM and dual athlon 1700+ XP CPUs. >Description: After the computer is booted and xinit is run, the first time I run Mozilla (from ports, mozilla-0.9.6,1) it locks up after a few seconds. My window manager is blackbox, I can kill the window in X, but I can't kill the process, even with kill -9. The process is stuck in the "run" queue: # ps -ax -O state | grep moz 140 R ?? R 0:02.47 ./mozilla-bin This causes the load average to be 1.00 even when the machine has both CPUs idle. Does not happen with other X apps, and running mozilla after that works correctly. >How-To-Repeat: I am not really sure why this problem started happening. I suspect it is something to do with the SMP kernel. Simply rebooting, starting X, athen running mozilla for the first time, is able to cause it to happen once on this (otherwise quite stable) machine. >Fix: No known fix other than to reboot. Its not really a problem other than causing the load average to always be 1 higher than it should be. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
