Some updates: After reading: <http://patchwork.kernel.org/patch/13610/> I found that booting the RHEL5 2.6.18-164 kernel with pci=nomsi the system boots and transfers normally. There is one fix regarding MSI that is not present in 2.6.18-164. Could you please try a test kernel available at: http://people.redhat.com/dzickus/el5/169.el5/ Thanks, Ivan. Brent, any results? Brent, could you please report if the proposed kernels for 5.5 are solving the issue? The latest are at: http://people.redhat.com/dzickus/el5/175.el5/ Ivan, I stress tested the 5.5 kernel and it performed perfectly. Here's the kernel information: [root@polaris ~]# uname -a Linux polaris.descension.net 2.6.18-175.el5 #1 SMP Fri Nov 20 19:32:16 EST 2009 x86_64 x86_64 x86_64 GNU/Linux From a second server I executed the following command to simulate 1000 downloads of a 87mb file off of the server running the new kernel: for i in `seq 1 10000`; do wget -nv --delete-after --append-output=polaris-175_stress-test.log http://polaris/rhel5/images/stage2.img; done It performed well and I did not have a single failure, where before with the RHEL 5.4 kernel it would fail after just a few downloads of the same file. I have attached the log to this bug report. Thanks! Created attachment 373444 [details]
kernel 2.6.18-175 stress testing
This upstream commit solves this issue: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f11a377b3f4e897d11f0e8d1fc688667e2f19708 This one was also used for solving bug #514589, so closing this one as a duplicate. *** This bug has been marked as a duplicate of bug 514589 *** |
Created attachment 359728 [details] testing results Description of problem: The r8169 driver stops working randomly during gigabit transfers. After putting it into 1000/full the machine will be able to transfer a couple of files (as tested through HTTP). It will stop seemingly after a couple of transfers and afterwards the machine is no longer reachable on the network. The corrective action is to reinsert the module (modprobe -r 8169 && modprobe 8169) to get networking functioning again. If the card is put into 100/full mode manually it works as expected.

Setup server running RHEL with NIC supported by r8169 (8168B) 2. Setup httpd to serve files 3. Server should autoneg to gigabit, but it can be tested by manually setting it with ethool 4. Transfer files to another server using wget on the same switch. Actual results: See attached file for test results Expected results: Server expected to have networking still working after several file transfers
