Hello,

I succesfully build a 2.6.38.8 kernel with the latest adeos patch and Xenomai 2.5.6, but it kernel panic :

Could it be a problem with the fact that this system is a virtual box VM ?

It is hard to tell, we do not have the error message, which should be
right above this stack trace. Please post the full logs, as there may be
other interesting details in the logs.

HI Nicolas,
For me similar panic was solved by adding
noapic and acpi=noirq options in Kernel Boot parameters while booting edit and add them and  please see if it helps.

Ok, I managed to have a few more trace, if you want more, I will have to enable framebuffer.

Because it is quite long, I will not copy it, I will send a screenshot.

Objet : RE: Kernel panic on boot with 2.5.6

HI Nicolas,
For me similar panic was solved by adding
noapic and acpi=noirq options in Kernel Boot parameters while booting edit and add them and  please see if it helps.

Subject: [Xenomai-help] Kernel panic on boot with 2.5.6
Hello,

I succesfully build a 2.6.38.8 kernel with the latest adeos patch and Xenomai 2.5.6, but it kernel panic :

What's your host system, Windows? If it's Linux, don't use VBox, use
QEMU/KVM (it's know to host Xenomai x86 without major problems, it's my
primary test platform for years).

What may help if you can't avoid VBox is to provide the host's CPU
frequency statically to Xenomai (xeno_hal.cpufreq=...) and enforce the
tsc as clocksource (clocksource=tsc). Timekeeping may go mad in the
guest, but it's for testing purposes only anyway.

Yes, my host is Windows, I can't change anything about that, and yes it is only for testing.

I changed my boot line : [    0.000000] Kernel command line: root=/dev/sda3 xeno_hal.cpufreq=1200 clocksource=tsc console=tty0 console=ttyS0,115200 noapic acpi=noirq video=vesafb:mtrr:3,ywrap vga=6

But I didn't find the range or the unit for cpufreq, and maybe I had to prefix clocksource with xeno_hal ?

But I noticed this in the log : 

[    1.202694] BUG: unable to handle kernel NULL pointer dereference at 00000920
[    1.202694] IP: [<c10736fe>] __xirq_end+0x12/0x2e

[    1.202694] Oops: 0000 [#1] SMP

Can it be because SMP is activated and that virtualbox is enabling only 1 processor with 1 core ?

Unit is HZ.

I don't know what vbox emulates in UP mode. We are only using it (for
Windows hosts) in SMP mode.

Found the problem !

It works on an Intel E5400 processor (for the host) but not on an Intel E2140


thanks for all.

So what was the problem? Looking at [1], I guess support for VT-x?

Running without VT-x means that vbox emulates a CPU. And that may be a
different type than what your guest kernel expects. Or that the modeling
is incomplete or buggy.

Virtualization without VT-x/AMD-V is no good idea anyway (way too slow).
