Hmm, shame this didn't work.

I'd have been interested to see the "xm dmesg" output from the "lapic"
case.

The lines

(XEN) Local APIC disabled by BIOS -- you can enable it with "lapic"
(XEN) Local APIC not detected. Using dummy APIC emulation

are a bit strange for me. The BIOS is quite simple PheonixBIOS with no 
options regarding APIC.
lapic kernel parameter was *surely* used

If lapic had been passed on Xen's command line then you would not have 
got the first line from Xen (the one that ends "...you can enable it 
with "lapic"").

It seemed strange to me too. But:
$ xm dmesg | grep lapic
(XEN) Local APIC disabled by BIOS -- you can enable it with "lapic"
$ cat /proc/cmdline
lapic root=/dev/hda6 ro console=tty1

Am I missing something?

Btw. I have tried live CDs on the notebook and 2.0.6 works fine (clock 
runs ok)
but 3.0 is again too fast.

You added it to the wrong command line. That's Linux's command line, 
not Xen's. If you boot via GRUB, 'lapic' gets added the line 
immediately above the one you currently added it to.

It's not that uncommon for the bios to disable the apic. I suppose it's
possible that Duron's don't have one anyway.

One thing that might be worth doing is to write a little program that
sits in a loop calling gettimeofday and reporting the delta from the
previous call [hint: convert the output into a 64b long long by
u.tv_usec + (unsigned long long)u.tv_sec*1000000; ]

It'll be interesting to see whether time runs forward smoothly or jumps
ahead in steps.

If time is progressing smoothly, then I guess the problem with your
laptop must be that the PIT that Xen uses is being subverted by
something else. No idea what, though -- perhaps something hidden in SMM.

Please can you try putting 'lapic' on the grub xen command line. Haing
the dom0 dmesg output would be useful too.

I think we only have one other current report of this 'time too fast'
bug, so it must be quite hardware specific.

I presume you're using 3.0.0?

I have trie lapic and nlapic with no noticable difference.

Yes I do. Compiled from mercurial.

Bad clock ticking in xen0

[Tomas Kouba]

[-- Attachment #1: Type: text/plain, Size: 576 bytes --]

Hi,
I have a problem with too fast clock in dom0.
The clock is 3-4times faster than 'real' clock.
In users list I got an advice suggesting that it is a hw bug. But I have 
no other problem with the hw and
I hope it is a xen bug (or my misconfiguration) and it can be fixed or 
workarounded.

It happens on a notebook compaq evo N115 (Duron 996MHz).
On my desktop with similar configuration there is no problem (xm dmesg 
attached for both).

I tried to locate the bug myself but with no luck :( Could you please 
suggest some hints where
to start debugging?
