Hi Tejun, Since this patch mentioned sunxi it gained my attention, but as it touches ahci core code I was expecting you to pick it up, which seems to not have happened, so hence this resend. FWIW I've tried to reproduce the problem, but it does not reproduce for me, that does not mean it is not a real problem though. I'm afraid I'm to unfamiliar with the ahci interrupt handling to say anything more sensible about this. It looks like this is a 3.18 regression, so if this is a real issue, we should probably get this patch in for 3.18 .
