Hi, I think it is the firmware, a similiar question came up on a SAMSUNG SSD 840 EVO. Reporter updated firmware and the failure disappeared. Here is link to upstream discussion, thanks. http://www.spinics.net/lists/linux-ide/msg50938.html The 850 Pro does not have any firmware updates at this time... In the meantime I'm wondering if I'm going to run into any problems? Found this patch, not sure if I should apply it; https://lkml.org/lkml/2015/5/19/451 (In reply to KernelBug from comment #2) > The 850 Pro does not have any firmware updates at this time... > > In the meantime I'm wondering if I'm going to run into any problems? I don't think so, it should be falling back to ATA_CMD_READ_LOG_EXT. > > Found this patch, not sure if I should apply it; > > https://lkml.org/lkml/2015/5/19/451 You can, it was committed. Thanks. commit eab6ee1ce3c4678224d70338134f7a02005768cb libata: Fix regression when the NCQ Send and Receive log page is absent Commited, what do you mean? It's going to end up in the kernel later? It seems to of been applied already, I'm using 4.1.6 So if the patch has already been added in, is it stil normal to get this msg? thanks Is this some hardware error that will cause problems, or is this a failure to read a log? thanks Hi, Even with the patch applied (Comment#3), it won't get rid of the message, but it will keep you from spinning in "READ LOG DMA EXT failed, trying unqueued", I don't think it will cause you any more errors. The problem is the drive advertises that it supports the DMA variant of READ LOG EXT, but it really doesn't so driver falls back. Thanks. Ok thanks... |
