Hi Joakim, First of all, thanks your care! Well, I dont think the above issue is exactly what we're hitting because DAR is correctly updated on our case with "dcbst". The problem is that it is treated as a write operation, but shouldnt. Maybe it is related to dcbst's inability to set DAR? BTW, about the CPU15 bug fix, has there been any effort to port/merge it in v2.6 ?
