Comment 19 for bug 105457

Actually it worked for me, but I have to remove everything related to MySql. So you can go to Synaptic Package Manager and search for mysql-, then sort it out by installed flag to get the found installed packages on top of list, then mark it for Complete Removal and finally apply the changes.

After that install only specific mysql packages as mysql-server-5.0 and mysql-client-5.0 (see attached screen-shot for detail).

Fill the difference:
1. No 100% CPU usage
2. mysqld is running instead of mysqld_safe
