Public bug reported:
for more than a week now, the kernel regressed in oneiric. My (quad-core)
desktop is now very slow. It seems to correspond to the
2.6.39-3 to 3.0-0 upgrade.
[ 35.650467] p4-clockmod: Warning: EST-capable CPU detected. The acpi-cpufreq
module offers voltage scaling in addition to frequency scaling. You should use
that instead of p4-clockmod, if possible.
[ 35.650622] p4-clockmod: P4/Xeon(TM) CPU On-Demand Clock Modulation available
