When periodically reading /proc/acpi/battery/BAT0/info (once
per second), running "adjtimex --compare=10000" indicates
slight slowing down of the system clock. It seems that
reading battery info may lead to loosing timer interrupts.
System: Compaq Presario 900Z notebook
Kernel: 2.4.21-ac1
First time the system clock drift was noticed when running
akpi applet for KDE: ntpdate time corrections were too
large. Then I've found that it happens when simply
To test this, run
adjtimex --compare=10000
in first xterm, and the following script on another xterm:
#!/bin/sh
for i in `find /proc/acpi/battery -type f`
do
echo $i
count=0
while [ $count -lt 30 ]
do
cat $i > /dev/null 2>/dev/null
sleep 1
count=$[count+1]
done
done
