Hello, We have started to use the em driver only recently, after the upgrade to gigabit connectivity (100 MBit NICs from Intel used the fxp driver). As for the frequency of the incidents, here is a grep of the messages: ~~~~~~~~~~~~ <slash> ~~~~~~~~~~~~~~ Aug 4 22:35:23 b2 kernel: em0: watchdog timeout -- resetting Aug 5 00:09:20 b2 kernel: em1: watchdog timeout -- resetting Aug 5 06:08:59 b2 kernel: em1: watchdog timeout -- resetting Aug 6 12:38:16 b2 kernel: em1: watchdog timeout -- resetting Aug 6 20:39:47 b2 kernel: em0: watchdog timeout -- resetting Aug 7 18:37:29 b2 kernel: em1: watchdog timeout -- resetting Aug 8 07:27:48 b2 kernel: em0: watchdog timeout -- resetting Aug 8 09:38:17 b2 kernel: em0: watchdog timeout -- resetting Aug 8 12:54:54 b2 kernel: em1: watchdog timeout -- resetting Aug 8 22:41:17 b2 kernel: em1: watchdog timeout -- resetting Aug 9 05:17:24 b2 kernel: em1: watchdog timeout -- resetting Aug 9 10:56:10 b2 kernel: em1: watchdog timeout -- resetting Aug 9 20:10:06 b2 kernel: em1: watchdog timeout -- resetting Aug 11 08:41:44 b2 kernel: em0: watchdog timeout -- resetting Aug 11 10:35:43 b2 kernel: em0: watchdog timeout -- resetting ~~~~~~~~~~~~ <slash> ~~~~~~~~~~~~~~ The driver used is version 3.2.18 (I wanted to use the Intel 6.1.4 as a module, but I have found out that I made a mistake and accidentally loaded the old 3.2.18 driver). I have dilemma now - which new driver to try? The 6.0.5 submitted to the current FreeBSD 6.1 branch (modified by you, I believe, on 8th August), or the newest driver from Intel 6.1.4? Do you think one of these drivers could solve my problems? I would be very thankful for any advice.
