When I try to upgrade from 5.1 to 5.2, the installer exits with signal 11. I don't think I am having hardware problems since everything else works fine and memtest says my memory is fine. This is on a Dell Optiplex GXpro with an Adaptec 2940 card. I've mostly tried installing via CD but have similar problems doing an FTP install.
OK, I'm an idiot. I had /var/tmp symlinked somewhere that no longer existed. I thought I fixed this but I must not have umount'd the fs after fixing it. I fixed it for good and everything is fine again. It would be nice if the install didn't syssegv but ... I bet you don't have so many idiots :) PS: /var is now in a very large partition and I won't have to symlink ever again, I swear :)
/var/tmp is a critical directory that must be present for the install to work poperly. We hope to account for things like this inthe future but fo rnow this is the way it must be.
