I know 2.6.3x kernels boots those boxes without a problem, that was the first thing that I tried. In any case, I'll try to find a way to solve that problem as 2.6.27.46 is the kernel that we are using on some nodes of Planet-Lab. If you (any of you) have any ideas/patches/solutions please feel free to share it with me (and I'll let you know If I can find anything). > thanks, > > greg k-h Best regards, -- S.Çağlar Onur <caglar(a)cs.princeton.edu> -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
