As before, I get errors using my Seagate SATA drives, and setting adma=0 fixes the problem. I've posted the exact error/reset messages several times before. However, I would like to note that it happens far less often with 2.6.22.1 than it did with 2.6.21. The history on my own machine is like this: 2.6.19 perfect, but of course no ADMA/NCQ 2.6.20 horrible, with hard resets starting immediately upon boot, and taking 15 minutes to finally disable NCQ 2.6.21 bad resets, but they only occured ever 10-30 minutes, NCQ never disabled 2 6.22 resets infrequent, they are soft resets, and much quicker than before (i.e. less interruption of my usage) NCQ is never disabled I have no idea why I might be seeing a gradual reduction in the severity of the problem, but it seems worth noting. I want to point it out in case it means something to anyone working on the kernel, especially the SATA code and drivers. In the last 4 hours of use, I've seen a single reset. On all previous kernels under the same load, I'd already have seen several of them, or with 2.6.20, a constant stream of them. -- shannon | An Irishman is never drunk as long as he can hold onto | one blade of grass and not fall off the face of the earth.
