em0 hangs without any messages like "Watchdog timeout", only down/up reset it.
Hello, Freebsd-stable.
My em0 (the same, copy'n'paste hardware info from previous
mnessage):
em0@pci0:0:25:0: class=0x020000 card=0x82681043 chip=0x10bd8086 rev=0x02
hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel 82566DM Gigabit Ethernet Adapter (82566DM)'
class = network
subclass = ethernet
bar [10] = type Memory, range 32, base 0xfea40000, size 131072, enabled
bar [14] = type Memory, range 32, base 0xfea79000, size 4096, enabled
bar [18] = type I/O Port, range 32, base 0xdc00, size 32, enabled
cap 01[c8] = powerspec 2 supports D0 D3 current D0
cap 05[d0] = MSI supports 1 message, 64 bit
cap 09[e0] = vendor (length 6) Intel cap 2 version 0
It is on-board LAN on Q35-based MoBo (ASUS P5E-VM DO)
It hangs under load without any output. When it works with POLLING, it
prints "Watchdog timeout" and reset automatically several times a day,
but without POLLING it simply hangs with same frequency. It is
8.2-PRERELEASE (from RELENG_8), cvsupped AFTER 22 Jan (last commit to
e1000 drivers family).
Locally system works, but mbufs are overfilled. "ifconfig em0 down
&& ifconfig em0 up" solves problem.
Output of different diagnostic tools (vmstat, netstat, ifconfig,
sysctl of dev.em.0 tree, top -S) are attached in one file.
Early (about half year ago) this sytem works without any problems
with net.
