Vlad, the fix for bug #1117 will not make it into 2.6.27 so I created the patch file ipath_0010_module-hangs-on-unload.patch into kernel_patches/fixes/ in the mean time. You can pull the fix from : url: ssh://git.openfabrics.org/home/ycote/scm/ofed_1_4/linux-2.6.git branch: ofed_kernel Thanks ! - Yan
