Hi Roland. During the last night many tests failed in our regression (new failure that appeared only during the last night).
It seems that destroy an AH causes a seg fault, i reproduced it using the ibv_ud_pingpong. Here are the machine props: ************************************************************* Host Architecture : x86_64 Linux Distribution: SUSE Linux Enterprise Server 10 (x86_64) VERSION = 10 Kernel Version : 2.6.16.21-0.8-smp GCC Version : gcc (GCC) 4.1.0 (SUSE Linux) Memory size : 5081168 kB Driver Version : gen2_devel-20070130-1817 HCA ID(s) : mthca0 HCA model(s) : 25218 FW version(s) : 5.2.0 Board(s) : MT_0150000002 ************************************************************* Driver Checksums: gen2_devel-20070130-1817 Kernel: Git: git://git.openfabrics.org/~vlad/ofed_1_2/.git commit ab8b772956b6178ef14c983fd215d0dda3fb6842 Kernel: Git: git://git.openfabrics.org/~vlad/ofed_1_2/.git commit ab8b772956b6178ef14c983fd215d0dda3fb6842 Here is the backtrace of the core dump: # gdb ibv_ud_pingpong core GNU gdb 6.4 Copyright 2005 Free Software Foundation, Inc.
