Hi,
At this moment I'm running FreeBSD 4.11 without any problems. A couple
of times I've tried to upgrade to 6.x but without any luck because of
the watchdog timeout errors on em0 when using nfs.
Mar 30 11:30:48 large kernel: em0: watchdog timeout -- resetting
Mar 30 11:30:48 large kernel: em0: link state changed to DOWN
Mar 30 11:30:51 large kernel: em0: link state changed to UP
Mar 30 11:31:01 large kernel: em0: watchdog timeout -- resetting
Mar 30 11:31:01 large kernel: em0: link state changed to DOWN
Mar 30 11:31:03 large kernel: em0: link state changed to UP
Mar 30 11:31:20 large kernel: em0: watchdog timeout -- resetting
Mar 30 11:31:20 large kernel: em0: link state changed to DOWN
Mar 30 11:31:23 large kernel: em0: link state changed to UP
em0@pci0:14:0: class=0x020000 card=0x002e8086 chip=0x100e8086 rev=0x02
hdr=0x00
vendor = 'Intel Corporation'
device = '82540EM Gigabit Ethernet Controller'
class = network
subclass = ethernet
When I try to copy a large file (1gb) then after a couple of mb's
(100mb) the wachtdog timeout will occur. The system is most of the time
idle. Using debug.mpsafenet="0" in /boot/loader.conf doesn't make
any
difference.
Any ideas?

Have you tried installing that? Jack

The server runs lighttpd on ufs, and the watchdog timeout occurs no matter whether there is heavy traffic. Here is some pciconf -l output which can be interesting. [root@me /usr/local/etc]# pciconf -l|grep em em0@pci5:0:0: class=0x020000 card=0x30a38086 chip=0x108b8086 rev=0x03 hdr=0x00 em1@pci6:5:0: class=0x020000 card=0x30a18086 chip=0x10768086 rev=0x05 hdr=0x00 Should more debugging aid / information is needed to narrow down the issue please let us know, thanks!
