Description Danny Tholen 2006-01-25 04:13:14 UTC

Acer Aspires used to have cpfreq problems because of broken PST tables. The 
powernow-k7 module works around this by falling back to ACPI. It seems more 
recent BIOS versions (3A29) have the problem again. This causes the cpu speed 
not to drop below 1450 MHz. Perhaps this version should be blacklisted as 
well. For more info, please look here:

The workaround there was "powernow-k7 acpi_force=1" on load.
Is this sufficient resolution? Does powernow-k7 require fixing? Or should this bug be closed.
Thanks.
