General error: 1548 Cannot load from mysql.. The table is probably corrupted


Please note there about 3 tables missing from 5.0 that are a part of 5.1. The best upgrade method is to dump your databases before updating to the 5.1 release. Move your old /var/mysql directory out of the way, setup /var/mysql again with the 5.1 data using the usual install initial database method and reload your databases.
