Package: powernowd
Version: 0.97-1
I have a system having an uptime of 267 days, where the output of /proc/stat
contains:
cpu0 1007769 1051077 4434830 2292814321 3357918 118001 4420102
Notice that the 5th columns contains a value larger than INT_MAX. This value
has to be converted by using strtoll. The powernowd uses strtol,
making a wrong conversion, resulting in a division by zero somewhere and no
frequency scheduling.
I'd like to propose the following patch:
$ diff -u powernowd.c.orig powernowd.c
