Attaching the tested patch.
we are getting problems also with kernel -89.0.9 in a HP DL585G2, which has a broadcom NIC: Ethernet controller: Broadcom Corporation NetXtreme II BCM5706 Gigabit Ethernet (rev 02) after some "heavy" traffic the network stop working. IF we restart the service, it will work again for a little while. The server do not panic and I am able to log into iLo console and check the stats. So far, we can see a lot of drops while working and then it stop when errors start reporting. for example: eth0 Link encap:Ethernet HWaddr 00:1B:78:BE:E8:5C inet addr:169.185.XXX.YYY Bcast:169.185.XXX.YYY Mask:255.255.255.128 UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RX packets:314613 errors:74 dropped:5503 overruns:0 frame:74 TX packets:188633 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:459977654 (438.6 MiB) TX bytes:45648574 (43.5 MiB) Interrupt:209 Memory:dc000000-dc012100 the problem disappear when MTU is set to 1500, or when we roll back to kernel -78.0.22 this is very easy to replicate in our environment, just with when creating a big tar file in local disk from a NFS volumen. wondering if you have a kernel to test with your patches included. I built rpms for x86_64 and i686 that have the firmware updated and the patch to bnx2.c as found in comment #1. Please see my people page http://people.redhat.com/jfeeney/.rhel4-bnx2/ Note that the firmware included in these rpms is a newer version than what comment #1 specifies (patch has version 4.6.16 and comment #1 has 4.4.2). I would appreciate it if this could be tested and the results reported back here. Thanks. sure John but would be possible to have the kernel-smp too? since we like to actually test the kernel with all 8 cpu availables thanks Okay, now the smps are on my people page too. Thanks. 2.6.9-89.14.EL.jfeeney.522119smp works on ibm-hs21-7995-2. Flavio Thank you, Flavio for the update. With this news, I am going to close this bz as a duplicate of bz523691 since it has the same fix as you provided. *** This bug has been marked as a duplicate of bug 523691 *** |
