Public bug reported:
The MSI MS-7093 motherboard using a Phoenix BIOS, has a known issue
where CPU frequency scaling does not work. Ubuntu 9.10 Alpha 3 attempts
to use the 'ondemand' CPU frequency scaler by default. The result is a
"white screen of death" where the entire screen turns white and the
system is unresponsive. This happens shortly after boot.
Workaround:
1. sudo apt-get install rcconf
2. sudo rcconf
3. Scroll down to 'ondemand' and disable it. Then restart.
Preferred Solution:
Ubuntu scans for this motherboard and automatically disables ondemand if it
finds it.
