Description Kevin Tian 2010-10-27 22:41:48 UTC 
my build system is 32bit Ubuntu9.04. When I tried to use task prebuilt to accelerate my build, it looks that sstate cache is not utilized although I didn't change anything between the two builds. Further check gave me different checksums, and then when I used bitbake-diffsigs below errors occur:

bitbake-diffsigs /media/disk/sstate-cache/sstate-zlib-native-i686-linux-1.2.5-r0-i686-1-6252843ebd096ed45f126dec4125f9d6_populate-sysroot.tgz /media/disk/sstate-cache/sstate-zlib-native-i686-linux-1.2.5-r0-i686-1-4c1abb703ea0b6f458c8160ec489178d_populate-sysroot.tgz

sorry a false alarm. I used wrong sigfile. :/
Comment 2 Kevin Tian 2010-10-27 22:51:00 UTC 
verify since it's invalid
