The machine is an old Dual-Core AMD Opteron(tm) Processor 1214 Hammer 2.2 G= hz, 4 GB of RAM and a ZFS rootfs. During the boot, the system becomes extremely slow as soon as init starts d= evd. After the boot, killing devd doesn't help, the system is still slow. When shutdown -r now is entered, the system remain slow until the machine reset. Tests done : I deactivated devd in /etc/rc.conf and the system is booting and working normally. As soon as I start devd manually, the system becomes slow. If I start devd -d, devd does not end of seg fault, it stays blocked on "Popping table" after an event is detected on ums0 mouse kernel module.=20 If devd is interrupted or killed, the system remains slow. If I boot on kernel.old (from 10.3 RELEASE), the system boots normaly and is working flawlessly. Booting on the new kernel having deactivated the ums module doesn't change = the devd behavior, it is still slowing down the entire system as soon it is started. --=20 You are receiving this mail because: You are on the CC list for the bug.=
