Hello again. I just find out something weird. 1_ I typed make menuconfig 2_ I went to "general setup" and unchecked "Automatically append version information to the version string" 3_ recompiled and installed the new kernel and suddenly all problems are disappeared. I am wondering why this option causes problems. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
