[20:36] <White_Light> I have been getting SATA errors on boot with the most recent 16.04 kernel. Specifically "WRITE FPDMA QUEUED" errors eventually followed by a hard reset of the sata link.
[20:36] <White_Light> This problem does not occur on 4.5.7, 4.6.6, or 4.7.0
[20:38] <White_Light> I have already swapped sata cables, and tried different sata ports - the error persists on the 4.4.0-34-generic kernel
[20:38] <White_Light> I'm using an asrock z77 z4 motherboard with a Crucial MX300 SSD - the motherboard has the most recent firmware applied as does the SSD
[20:39] <White_Light> These sata errors only occur at boot, they delay the boot by up to 10 minutes, but after that the SSD performs normally
[22:22] <JanC> White_Light: I can't help you, but make sure to file a bug report too (if you didn't already)
[22:23] <White_Light> I was hoping this was a known issue, I have no faith in a bug report resulting in any fix before the HWE comes out in February
[23:39] <JanC> White_Light: if everybody thinks that, then it will never be a known issue
[23:43] <JanC> (and the kernel developers would need the info that gets added to a kernel bug to know if it is a known issue anyway)
[23:59] <White_Light> JanC, important customers and widespread problems would get faster attention and therefore it would be worth reporting
[23:59] <White_Light> I'm neither important nor am I experiencing a common problem - it will take months to even get acknowledged so I'll just run mainline kernels
