Title:
[Dell Latitude E6520] After suspend, machine very slow with ondemand
governor
Status in “linux” package in Ubuntu:
Fix Released
Bug description:
After several suspend/resume cycles and several days of uptime, using the
ondemand governor the system is very slow to answer some inputs. The text
output pauses for several seconds while I am typing this text. Trying to scroll
a firefox window takes several seconds. Switching tabs in firefox takes several
seconds:
cat /sys/devices/system/cpu/c*/cpufreq/scaling_governor
ondemand

ondemand
WORKAROUND: Setting the governor to "performance" fixes this problem.
