Public bug reported:
After last nights update (update-manager) old laptop was no longer able
to play video or flash-video fast enough, (looked like a slid-show at
best) though the audio worked fine.
Booting into 2.6.32-38-generic fixed the issue, but
echo $(uname -r) $(cpufreq-info |grep 'current policy'|sed 's/.*within//')
2.6.32-38-generic 800 MHz and 800 MHz. 800 MHz and 800 MHz.
(though this may be /etc/init.d/ondemand kicking in.)
(Lucid Linx on Intel Centrino Duo Dell Latitude D420 with 2Gig of RAM)
I have checked the BIOS and SpeedStep is enabled.
If I boot into 2.6.31-14-generic then the 'current policy' is "800 MHz
and 1.20 GHz"
cat /proc/version_signature
Ubuntu 2.6.32-38.83-generic 2.6.32.52+drm33.21
