This is an odd one which I will continue to try to debug.
A recent change added CONFIG_MAC80211_MESH to the fedora kernel. Oddly
this causes gcc to hang when building net/mac80211/debugfs_netdev.c. I
originally suspected a gcc-4.3 bug but I then reproduced this on RHEL5
This code is not yet in Linus's tree. Could someone point me to the git
tree where it lives? I am thinking a git-bisect may help me find the
specific change that causes this.
In the meantime it would be greatly helpful if we could add the
following to config-ia64 and config-ia64-generic:
# CONFIG_MAC80211_MESH is not set
This along with the change to not apply the utrace patch (see my earlier
mail) once again allows ia64 to build.
