loadavg question

[Boszormenyi Zoltan]

Hi,

on an embedded PC (500MHz AMD Geode), we recently tried
to upgrade the kernel. The original version was 2.6.27, the new
ones were 3.3.x and 3.7.x. With the same userspace (a GTK based
GUI constantly querying daemons handling different pieces of
hardware over serial ports), we noticed that loadavg is different
while the idle time (95-97%) is the same. On 2.6.27, the load was
around 0.05-0.3 while on 3.3.x and 3.7.x, it quickly crawled up
to around 5. Has the load calculation changed so dramatically
after 2.6.27?

Thanks in advance,
Zoltán Böszörményi
