Thanks for the report. What we have is: 6.6: gcc-4.4.3 6.7: gcc-4.5.1 6.8: gcc-4.5.2 7.0: gcc-4.6.1 Fernando, I believe you have these systems running. Can you confirm that kmod-14 breaks with gcc-4.5.2 but is successful with gcc-4.6.1. > Another thing, the HSR lists a minimum running 2.6.25 kernel, but > building glibc 2.18 needs --enable-kernel=2.6.34.

Since we are building a current kernel, for reboot, then the setting of 2.6.34 if OK, even though we might be using an earlier version while building glibc. > Sorry, just a newbie here.
