I have *no* idea what caused it. Possibly my (bad) gfs2/dlm patch... Please try applying Adrian Bunk's patch to see if that fixes the IPV6 disappearing trick.

Yes, patch below. > regards, cu Adrian <-- snip --> This patch fixes a circular dependency by letting GFS2_FS_LOCKING_DLM and DLM depend on instead of select SYSFS. Since SYSFS depends on EMBEDDED this change shouldn't cause any problems for users.
