i am running kernel 2.6.28.15 on a gigabyte mainboard with two Realtek Ethernet
8111D chip sets.
On a all Gigabit Ethernet network. (it seems there are no problems on a 100Mb
network)
config: Gigabyte GA-EX58-UD5 , CPU: Core i7 - 950, RAM: 6x2GB Corsair
dominator TR3X6G1600C8D
Onboard Ethernet controller: Realtek 8111D , 4x1TB in raid10 configuration
A am experiencing disconnects when reviving large amounts data form a
other network hosts.
After about 45 seconds of heavy load (smb copy of about 224Mbit/s) my
NIC also stops working for one minute.
If i do a continuous ping form this system it's stops whit the messages “Ping
: Sendmsg : No buffer space available”
but the nic only returns after the ping has stopped. ( is this a clue for
somebody ?)
If the NIC returns after the first failure and the network load resumes
the NIC almost direct stops working again. Adding extra sessions to the
NIC seems to expedite the situation making the time till this failure
occurs even shorter.
Does everybody have a solution for this bug. I heard that that complying
the driver form the realtek webside solved the problem?
Is this the solution for this bug? Is it going to be included in the
new kernels?
I need this bug fixed before I can put this machine in production and
team the nic's together and add 802.1q support.
i included the output of my machine below..
