I've compiled the new driver and installed it. I'll schedule a reboot later this week to get it working. I've also built 2.6.14.3, which was activeted by a reboot this Saturday. I'll let you know if the new driver worked. >do you have a test to reproduce this? Yes, let the server act as usual, it just starts happening out of the blue. No new hardware has been added or removed, no new programs has been installed. Only thing upgrades was the kernel. >Thanks, Jesse Thanks, Andreas
