After 22 minutes of production running i have watchdog timeout with new em driver: root@movieserver:~# uname -a FreeBSD movieserver 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #0: Tue Oct 31 11:00:14 EST 2006 root@movieserver:/usr/obj/usr/src/sys/GENERIC i386 Oct 31 12:22:12 movieserver kernel: em0: watchdog timeout -- resetting Oct 31 12:22:12 movieserver kernel: em0: link state changed to DOWN Oct 31 12:22:15 movieserver kernel: em0: link state changed to UP Average load on this em card is ~ 5000-6000 interrupts per second. BUT i want to admit that i have watchdog timeout problems ONLY with this chip: em0@pci3:2:0: class=0x020000 card=0x10118086 chip=0x10108086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82546EB Dual Port Gigabit Ethernet Controller (Copper)' class = network subclass = ethernet on all my servers regardless of UP or SMP kernel. I have even box with FreeBSD 5.5 with such em timeouts. -- ====================================================================== - Best regards, Nikolay Pavlov. <<<----------------------------------- ======================================================================
