Hello.
Some days before, I tried to run CoLinux 0.8.0 in one Virtual PC Windows
XP session. Short summary: It did not work. It is not possible for me to
judge whether CoLinux may be corrected to run in Virtual PC or if this
is one real serious problem.
Thus, i ask the list: Do you think that it will be possible to run
CoLinux with Virtual PC?
Best regards,
Nico
An older version did not run with error:

This is the line
BUG_ON(!irqs_disabled());
Think, we can fix it. Our timer callback leaks somethere with enabled
interrupts. I'm afraid.
As workarround set loops_per_jiffy manualy as kernelparameter and skip
the calibration: "lpj=3000000" (see kernel source
Documentation/kernel-parameters.txt:910)
We currently have kernel 2.6.22.18 and some changes on the proxy
interrupt handler. Please give the latest snapshot a try. If that also
fails, then send please the new stack trace again.

The driver is not loaded correctly.
First, please run this and send me your result:
* cd C:\colinux
* colinux-daemon --status-driver
To fix it, please do follow steps
* cd C:\colinux
* colinux-daemon --remove-driver
* colinux-daemon --install-driver
* colinux-daemon --status-driver
If that not helps, then reboot windows between remove and install.

Hello Henry.
Thanks for your quick answer. I needed some more time and did tests with
and without the proposed "lpj" kernel parameter.
The results:
lpj=3000000

lpj=1000
========
Slows down the Virtual PC in a way that you believe that the Virtual PC
does not work anymore. The VirtualPC process takes 100% of the
performance of one of my processors. Fortunately, I have two of them. ;)
The last line in the concole is:

lpj=5000000
===========
Same behavior as with lpj=1000.
Lpj=3000000 again
=================
Now, it stops at line

Without lpj

At the end of every of the "lpj" tests I had to restart VirtualPC
because it hangs.
Do you have another proposal?
