Hi Dave, while working on an NFS problem (Ubuntu/Hardy) I needed to get definitions of 'struct svc_cacherep'. I have compiled nfsd.ko with debugging for an older kernel. Current kernel: 2.6.24-24-generic nfsd.ko: 2.6.24-21-generic The definition of 'struct svc_cacherep' is the same. To avoid rebuilding nfsd.ko I decided to specify /boot/System.map-2.6.24-generic explicitly. Before loading 'nfsd.ko' the address of 'lru_cache' variable is correct, but after loading old nfsd.ko it changes: crash32> sym lru_head f908b988 (b) lru_head crash32> mod -s nfsd /usr/lib/debug/lib/modules/2.6.24-21-generic/nfsd.ko MODULE NAME SIZE OBJECT FILE f908a280 nfsd 228976 /usr/lib/debug/lib/modules/2.6.24-21-generic/nfsd.ko crash32> sym lru_head f908b984 (b) lru_head Is this expected? It would be nice to be able to give precedence to symbols as defined in System.map (maybe a startup option or internal set option).
