Hi!
Kernel 2.6.37.6 and Xenomai 2.5.6 boots ok, though displaying the error
message: "MP-BIOS bug: 8254 timer not connected to IO-APIC".
If I try to use Xenomai 2.6.1 the error message displayed is the same
and system just hangs after that. No other messages, keyboard doesn't
work, nothing. I started with the same kernel configuration, but I have
disabled a few options more (e.g. syscall auditing, shared interrupt
support).
I'm using Intel Core 2 Duo processor with Asus P5LD2-VM motherboard.
Obviously I'm missing something, but I can't figure that out. Here is
the kernel config file:
If you use one of the I-pipe patches whih ship with Xenomai 2.6.1, such
as the patch for linux 3.2, do you also have the issue?
Hi!
Yes, I have patched the kernel with this:
/usr/src/xenomai/scripts/prepare-kernel.sh --arch=x86_64
--adeos=/usr/src/xenomai/ksrc/arch/x86/patches/adeos-ipipe-2.6.37.6-x86-2.9-02.patch
--linux=/usr/src/linux
xenomai being a link to xenomai-2.6.1 -directory. When I switch between
Xenomai 2.5.6 and 2.6.1 I remove the whole linux directory and extract
it from the source again and change the xenomai link accordingly. With
Xenomai 2.5.6 the patching was done with this:
/usr/src/xenomai/scripts/prepare-kernel.sh --arch=x86_64
--adeos=/usr/src/xenomai/ksrc/arch/x86/patches/adeos-ipipe-2.6.37-x86-2.9-00.patch
--linux=/usr/src/linux
So, could you try Xenoami 2.5.6 with the 2.9-02 patch, or 2.6.1 with the
2.9-00 patch, or with the patch for linux 3.2 ?
I booted 2.6.37.6 kernel patched with 2.9-00 patch and compiled Xenomai
2.6.1 with the following commands:
I mean Xenomai 2.6.1 kernel with the 2.9-00 patch or Xenomai 2.5.6
kernel with 2.9-00 patch. Since the kernel is not booting, we do not
care about the user-space at this point.
I tested again the following combinations. Always starting with a fresh
kernel tree and patching it:
2.9-00 patch 2.9-02 patch
----------------------------------------------
Xenomai 2.5.6 OK OK
Xenomai 2.6.1 boot fails boot fails
Hi,
I could reproduce the bug, it should be fixed with the following patch:
http://git.xenomai.org/?p=xenomai-2.6.git;a=commitdiff;h=28984e66e9e17701354f8883b025fcf83f8b0b68;hp=8417949f5e7d1b4483eb3b6344ec5f3124ecf740
This patch fixed the problem. I tested this with Core 2 Duo processor
and hopefully I have time tomorrow to test it with Atom D2500 board also.
Thank you for your help!
Best regards,
-Jari
