I described a potential race between DMA and CQ updates on Altix systems. At that time the bug hadn't been observed, but was expected to be possible on "large" NUMA systems. A first-cut at a patch was sent out, some very reasonable objections were raised, and the thread fizzled out. Since that time we've been able to produce the bug, and show that the patch I sent fixes the problem. (OK, the patch I sent with the addition of a small but important patchlet.) The biggest concern with the earlier patch seemed to be backward compatibility. There was a stab at addressing that in http://tinyurl.com/2x3s52, but no commentary. (Too ugly for words?) Any suggestions as to how to proceed? Should I just code something up in order to have a concrete target to discuss? Or are there any new thoughts based on the previous emails? -- Arthur _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
