When upgrading my debian box from kernel 2.6.18-4-k7 to 2.6.21-2-k7, pppstatus
starts (when the system is connected to the internet) eating up more than 50% of
CPU (top display), increasing the load remarkeably and slowing down the system
to an annoying extent.
I think the underlying problem is the 'usleep (10L);' call in pppstatus.c,
l.2087: kernel 2.6.21 seems to meet the sleep time of only 10 microseconds (!)
much closer that kernel 2.6.18. Thus the pppstatus processing loop runs almost
without any pause, eating up the whole CPU time it gets.
The attached minimal C program demonstrates the usleep differences between both
kernels, the attached outputs result from running it ten times on my box.
When patching the usleep call to 10.000 microsends, CPU usage decreases to the
used level and my box becomes fluently usable again.
