I have recently raised the following issue in freebsd-questions and in
comp.unix.freebsd.misc. I guess I am still hoping to get a definitive
answer one way or the other.
I would very much like to know whether FreeBSD is fully functional on
this machine. That is, even though it appears normal except for the
output from top and ps, is the kernel malfunctioning in some way? Is
it safe to use this machine as a router or firewall?
kernel: 4.4-STABLE
motherboard: P2L97-DS, dual Pentium II 300MHZ
top shows 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 0.0% idle
WCPU and CPU show 0.00% for all processes in top and ps.
This problem appears in google alot. The standard solution is to
compile userland after compiling a new kernel, but this doesn't solve
it for me. Others have mentioned this problem with this motherboard,
but no resolution appears to have been made.
Actually when I boot then log in immediately, I can see some non-zero
percentages appear in top (like sshd and top itself). All processes
gradually reduce to zero percent, however, and never come back. For
example, a 'make buildworld' will put make and cc at the top, but they
still say %0.00 along with all the other processes.
It runs fine with kernel.GENERIC, so I am assuming the problem is a
result of enabling SMP. Top runs fine with SMP linux.
I have
- upgraded bios.
- cvsup src-all 4.4-STABLE
- build kernel, reboot, build world
- enabled mps 1.4 support in bios (tried it disabled too)
LINT config file says
# Notes on APM The flags takes the following meaning for apm0: 0x0020
# Statclock is broken. If apm is omitted, some systems require sysctl
# -w kern.timecounter.method=1 for correct timekeeping.
but all combinations of setting apm on/off and setting
kern.timecounter.method on/off do not correct the problem (I reboot
each time to be sure).
I tried the follwing patch I found on google archives but it didn't
seem to help (I thought it did at one point --- before I watched top
long enough to realize the percentages were falling).
Please CC my email if you reply.
Thanks.
