[Bug 17589] System clock runs far too fast

Comment:
My clock still runs at double speed, even with the latest kernel Dapper.

However adding the boot parameters "noapic acpi=noirq" fixes the clock
problem.

The approximate drift on my system is:

Feb 10 07:44:05 soekris.alcor.net ntpd[4699]: time reset +3.107237 s
Feb 10 07:56:02 soekris.alcor.net ntpd[4699]: time reset +3.555953 s
Feb 10 08:11:10 soekris.alcor.net ntpd[4699]: time reset +3.117062 s
Feb 10 08:29:37 soekris.alcor.net ntpd[4699]: time reset +3.792346 s
Feb 10 08:46:51 soekris.alcor.net ntpd[4699]: time reset +3.404976 s
Feb 10 09:06:16 soekris.alcor.net ntpd[4699]: time reset +4.350930 s

(the same net4501 486-based system) Would it be useful to try
disable_timer_pin_1 or another parameter on this hardware?

Do you have a FSB Spread Spectrum in your BIOS setting?

disable_timer_pin_1 on my system stops it booting - it hangs just after
showing the splash screen.

I do have a FSB Spread Spectrum setting in my BIOS, it is set at 0.5

I can confirm this bug in dapper flight 5.

ubuntu 2.6.15-18-386
on an HP laptp (ze2355ea) AMD Turion 64

I have tried booting using the kernel parameters suggested above 'noapic
acpi=noirq" and then with "noapic acpi=off" but neither seam to fix the
problem.

"Do you have a FSB Spread Spectrum in your BIOS setting?"

No.

This sounds similar to http://bugzilla.kernel.org/show_bug.cgi?id=5038 Could those of you experiencing this bug try some of the tests/workarounds there?

[Crispin Flowerday]

Booting with 'noapic' as mentioned in the kernel bug seems to solve the problem for me.

I have the same problem running Dapper Drake on an Intel Core 2 Duo
desktop (Asus P5WDG2 WS Pro motherboard) with Nvidia graphics on the
latest 2.6.15-26-amd64-xeon kernel package 2.6.15-26.47

[Andrew Pam]

Using the "notsc" kernel parameter seems to fix the problem.

[p2k]

The clock of my Shuttle SN41G2/Athlon XP 3000+ desktop with Nvidia
nForce2 chipset is running too fast: it gains about 3 seconds per 10
minutes (verified running 'ntpdate ntp.ubuntu.com' every 10 minutes).

I'm running Dapper Drake 6.06.1, kernel 2.6.15-27-k7, fully apt-get
updated/upgraded.

The default tickadj is 10000.

sudo tickadj 9950

I have the same problem with a VIA Samuel 2 (Cyrix C3) CPU on a VIA EPIA
motherboard. Kernel timekeeping was fine with the 2.4 kernel, but broke
with the 2.6 kernels. On that server I'm currently running kernel
2.6.16.29 with debian patches under debian stable, but have previously
run kernels from 2.6.8 onwards all of which have this problem. This
server is running ntpdate every 5 minutes and has gained 1.7 seconds
each time, which sounds the same as your report. I'll have to try
tickadj and see if it helps.

Andrew

I was having this problem with a computer and I did the following to get
it under control:

$> cat /etc/ntp.conf | grep burst


server ntp.ubuntu.com burst iburst

server pool.ntp.org burst iburst

That sends 8 packets instead of just 1 to the ntpserver.

The real fix for this problem was replacing the CMOS battery in the
motherboard. After that, ntp just work.

[Martin Kalén]

FYI p2k and others: on Shuttle motherboards the system clock frequency
can suffer badly from CPU over-clocking. This is not specific to any
operating system and was verified with a Shuttle SN45 under Ubuntu,
Slackware and Windows XP. With CPU frequency settings set to
"Aggressive" in BIOS, my clock was running way too fast (everything from
a few seconds to fast per 1-10 minutes up to double speed with two
second ticks per wall-clock second). Settings CPU speed to "Optimal" in
BIOS solved the problem for me.

(CPU: AMD Sempron 2800+. Additional BIOS settings: ACPI=ON, MPS-
level=1.4, Memory timings=Aggressive, C1 disconnect=AUTO.)

My clock runs too fast since I upgraded to Hardy Heron. I have an intel
Core Duo T2500.

I have never had this problem until I upgraded my Gutsy installation to
Hardy.

I marked some bugs as (possible) duplicates of this bug.

[Launchpad Bug Tracker]

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu
kernel bugs need to be reported against the "linux" kernel package. We
are automatically migrating this linux-source-2.6.15 kernel bug to the
new "linux" package. We appreciate your patience and understanding as
we make this transition. Also, if you would be interested in testing
the upcoming Intrepid Ibex 8.10 release, it is available at
http://www.ubuntu.com/testing . Please let us know your results.
Thanks!

[Leann Ogasawara]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-
image-2.6.27-* package is currently available for you to install and
test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer
2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4.
Please watch http://www.ubuntu.com/testing for Alpha5 to be announced.
You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the
bug reported here or if the issue remains. More importantly, please
open a new bug report for each new bug/regression introduced by the
2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please
specifically note if the issue does or does not appear in the 2.6.26
kernel. Thanks again, we really appreicate your help and feedback.

With the latest kernel I still have this problem. The time corrects
itself upon rebooting.

[am28111]

Upon further investigation, it seems that turning off Auto intelligent
stepping in the Foxconn BIOS corrects the problem.

[ubuntu_demon]

For me using clock=pmtmr works as described here :

This bug report was marked as Confirmed a while ago but has not had any

This is still a very current bug. I have had it since Intrepid and are
now running Karmic Koala. I have a ATI 1959 Pro Graphic card and Intel
dual core processor. I have a Asus P5W DH Deluxe motherboard. I have
tried a couple of fixes without luck.

I am also experiencing this problem; it is new to me since upgrading to
karmic. I am on an Intel P4 system. Not sure what other info is relevant
but if anyone needs any info just let me know. Cheers.

[eniton]

Experiencing the same issue. I deployed Ubuntu server 9.10 to 20
servers. All servers sync the clock everyday, but the system clock in
each would be seconds different with others. It's annoying and dangerous
for our distributed computing model.
