OK, thanks. >> But the CP is still broken: > > Is this a regression? ?If so, can you bisect it? Yes. But looking at my logs the regression did not happen from 2.6.34->2.6.35 but from 2.6.33 to 2.6.34. The first failed ring test was with the Gentoo 2.6.34 kernel, but all the working bisect steps between 2.6.34 and 2.6.35-rc4 also failed. I will try to bisect this tomorrow, but I'm not sure if this will work, because 2.6.34 is not really working for me.
