Greetings Everyone, Along this same topic, I have also had a problem with 9-STABLE being unstable. I have been experiencing random kernel core dumps on a machine. I know the machine is fine, if i switch back to a set of disks running my previous 8-stable everything is fine. But with a current 9-STABLE as of last night even I get kernel panics. Can provide more details tomorrow, machine is currently panicked in the data center and need to go there in the morning to reboot. Hoping it gets fixed soon, want to start bringing the machine into production slowly, don't want to have to roll back to 9-release would rather see this fixed. But i believe it is a variation of the exact same problem that has been brought up here. Last panic it created a core file, hopefully it did again so i can debug it.
