--- Comment #20 from Julien Cigar <jci...@ulb.ac.be> ---
Hello,
I'm running 10.2-RELEASE on a HP Proliant Microserver with the following
network interface:
em0@pci0:2:0:0: class=0x020000 card=0xa01f8086 chip=0x10d38086 rev=0x00
hdr=0x00
vendor = 'Intel Corporation'
device = '82574L Gigabit Network Connection'
class = network
subclass = ethernet
The machine run an NFS server and unless I mount the shared folder with a
rsize/wsize of 32768 I'm experiencing watchdog timeouts after a few minutes
under load (for ex streaming a movie):
Nov 7 23:25:26 mordor kernel: em0: Watchdog timeout Queue[0]-- resetting
Nov 7 23:25:26 mordor kernel: Interface is RUNNING and ACTIVE
Nov 7 23:25:26 mordor kernel: em0: TX Queue 0 ------
Nov 7 23:25:26 mordor kernel: em0: hw tdh = 508, hw tdt = 402
Nov 7 23:25:26 mordor kernel: em0: Tx Queue Status = -2147483648
Nov 7 23:25:26 mordor kernel: em0: TX descriptors avail = 93
Nov 7 23:25:26 mordor kernel: em0: Tx Descriptors avail failure = 0
Nov 7 23:25:26 mordor kernel: em0: RX Queue 0 ------
Nov 7 23:25:26 mordor kernel: em0: hw rdh = 206, hw rdt = 205
Nov 7 23:25:26 mordor kernel: em0: RX discarded packets = 0
Nov 7 23:25:26 mordor kernel: em0: RX Next to Check = 206
Nov 7 23:25:26 mordor kernel: em0: RX Next to Refresh = 205
Nov 7 23:25:26 mordor kernel: em0: link state changed to DOWN
Nov 7 23:25:30 mordor kernel: em0: link state changed to UP
... and I have to do an "hard" reboot
