Hi, I'm still seeing watchdog timeouts on my em card using stable from Nov 28. Before the flurry of messages/activity about this last month I never had any timeout problems, they only started occurring after the em changes were committed in November. Generally when the timeout occurs everything hangs for a bit (30-60 seconds maybe?), then resumes normal activity. Please let me know what I can do to help. Thanks, Brad # the log file starts on the morning of the 11th root@backup[/var/log][119]% grep -i watchdog messages Dec 11 11:38:49 backup kernel: em0: watchdog timeout -- resetting Dec 11 12:07:03 backup kernel: em0: watchdog timeout -- resetting Dec 11 19:35:26 backup kernel: em0: watchdog timeout -- resetting Dec 11 20:33:07 backup kernel: em0: watchdog timeout -- resetting Dec 11 23:03:35 backup kernel: em0: watchdog timeout -- resetting Dec 12 06:06:58 backup kernel: em0: watchdog timeout -- resetting Dec 12 14:05:28 backup kernel: em0: watchdog timeout -- resetting Dec 12 19:02:12 backup kernel: em0: watchdog timeout -- resetting Dec 12 19:06:43 backup kernel: em0: watchdog timeout -- resetting Dec 12 20:02:46 backup kernel: em0: watchdog timeout -- resetting Dec 12 20:03:54 backup kernel: em0: watchdog timeout -- resetting Dec 12 21:15:37 backup kernel: em0: watchdog timeout -- resetting Dec 12 23:05:24 backup kernel: em0: watchdog timeout -- resetting Dec 13 01:38:36 backup kernel: em0: watchdog timeout -- resetting Dec 13 02:35:26 backup kernel: em0: watchdog timeout -- resetting Dec 13 11:37:27 backup kernel: em0: watchdog timeout -- resetting Dec 13 19:47:56 backup kernel: em0: watchdog timeout -- resetting Dec 13 20:29:45 backup kernel: em0: watchdog timeout -- resetting Dec 13 23:35:00 backup kernel: em0: watchdog timeout -- resetting Dec 14 06:35:40 backup kernel: em0: watchdog timeout -- resetting root@backup[/var/log][120]% uname -a FreeBSD backup 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #0: Tue Nov 28 17:52:48 PST 2006 root@backup:/home/obj/usr/src/sys/BACKUP i386 - debug.mpsafenet is already 0 because I have ipsec enabled. - I'm using PF/altq - Polling is compiled into the kernel but not enabled, HZ=1000 - em0 is a PCI card, not on board, with jumbo frames enabled.
