So you _had_ a working self-compiled 2.6.30 kernel at some point? Yes, my case is very similar to the one described by Kiko Piris, and I also think this is getting off topic. > One thing to look out for is that a compiler upgrade/downgrade will be > invisible to the kernel build system, so if you downgrade the compiler > and recompile, you may not actually recompile things at all. I tried the bisect with the same compiler and then for other tests I recompiled from scratch each time on a tmpfs to make sure I was not messing things up. On this machine, ccache is not used. So I am suspecting a recent glibc or binutils upgrade (gcc downgrade did not solve the problem) and even if some people noticed problems with 2.6.30.2, my issue seems different and only distro-related. -- Damien Wyart -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
