I am not able to get the mutlicast send/recv test programs to work on pSeries on any kernel, including the very latest IBM patches for 2.4.21-pre3. Do you have any setup where this works? (pSeries, Linux, pcnet32)? ------- Additional Comments From lge.com 2003-01-29 12:00 ------- The systems I used for the tests are 2 p640s with RedHat 7.1, 2.4.9 kernel. And the network adaptor used is AMD PCNET32. David Stevens (LTC networking team) and I digged into the problem a little bit, we found out most likely it is a pcnet32 device driver problem. Does this mean that someone at IBM will work on a fix? Created attachment 90190 [details]
multicast fix for pcnet32
The attached patch corrects multicast receive on pcnet32 devices.
Note that the LTP multicast test has an implementation error that can cause it
to fail when using hostnames. To be sure the test runs correctly, use IP
addresses instead.
Fixed in current release An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
