The immediate cause of this is pretty simple to fix, the sg passed to process_startdone_barrier_new() has a NULL sevent in some cases (the deeper question is why). The function immediately references sev->flags without checking for NULL which leads to the oops above. We now just print an error and return if the sevent is NULL instead of oopsing. cvs commit: Examining . Checking in sm_barrier.c; /cvs/cluster/cluster/cman-kernel/src/Attic/sm_barrier.c,v <-- sm_barrier.c new revision: 1.1.2.2; previous revision: 1.1.2.1 done The reason process_startdone_barrier_new() is being called with a NULL sevent is bug 206193. Just mounted 65 gfs filesytems simultaneously on a 4 node cluster. Marking verified. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below.
