Tickless is in there and enabled, but only the i386 code is in that
kernel. We will probably end up disabling tickless by default but
leave it possible to enable with "nohz=on". For now if anyone has
problems, try "nohz=off" and/or "highres=off".
My system starts and runs OK, but I notice a problem I had not seen
before. The Dell D820 has a dual core processor and between 10 and
30% of one of them is consumed by a program "automount", according to
top. This is happening when the system is idle--no disks going in, no
changes in network. Here's a snapshot where top says automount is
taking half of the cpu.
2013 root 20 0 6140 1148 912 S 50 0.1 31:47.71 automount
On the other hand, other machines that are not running the new kernel
do show an automount process running, but it takes 0 CPU time, as in:
root 2221 0.0 0.0 93184 1228 ? Ssl Jul12 0:02 automount
Isn't scanning for new device insertions one of the things that is
affected by timings?
The hpet support is found and used, according to the dmesg output:
Time: hpet clocksource has been installed.
Switched to high resolution mode on CPU 0
Switched to high resolution mode on CPU 1
but later on I notice a stray
hpet_resources: 0xfed00000 is busy
