The latest MRG 2.0 errata kernel has updated NIC drivers. There are updates to the bnx2 driver which is what your lspci shows you have. Please the current errata package for kernel-rt: kernel-rt-2.6.33.9-rt31.75.el6rt Hi, I do not have anymore that server (nor anything similar) so cannot do additional testing for me this is no more an issues as I've no more boxes currently using that kind of hardware+software combination Ok, we'll close it then |
Created attachment 498005 [details] messages + lspci Description of problem: On a dell t100 we are getting network card crash/hangs (tg3) Version-Release number of selected component (if applicable): kernel-rt-2.6.33.7-rt29.55 How reproducible: workload not very high in terms of bandwidth. pps is around 10k in+out... 99% of the traffic is UDP. Actual results: From time to time the network card hangs... load start climbing... it autoreset itselft after minutes (certain times 1min is enough, other it takes up to 30minutes) This does not happens very often... it happened 2 times on a 5days timespan. Additional info: cpu: xeon X3330 seeing the second event log it reverted to hpet because tsc appeared unstable. After the second even we did not tried it again... currently can't afford additional downtime so it's running on the non-rt kernel using jiffies clocksource and appear to be rock solid. Could TSC be the problem?
