Hi, all.

This is Result about Booting using linux-2.6.29-rt2 Kernel on X86 Targets.
I used below desktop and netbook in this test.

I read RedHat Bugzilla's pages about the problems.
for example,
https://bugzilla.redhat.com/show_bug.cgi?id=479188

Anyone have this problems on Fedora Linux Distribution with linux-2.6.29-rt2 ?

I solved  mounting error  with "acpi=off  noapic nodma" options about
below problem .
 ( reference : ./linux-2.6.29-rt2/Documentation/x86/x86_64/boot-options.txt )
Hope this helps for fedora users.
This is kernel issues? In fact, I am not sure.
Thanks reading.

Ouch. That's not a real solution.

Hmm. You said the same kernel works fine on other distros, right ? Do
you use the same .config for the different distros. If not you could
try to build the kernel on fedora with the other-distro config.

Thanks,

Dear Thomas,

Thank you for your fast response.

I think so.
But, I need trick for  kernel booting on Q9300 &Q8200Target successfully.

Yes.
I used the same kernel on various distros as I said previously.
( config file :
http://leemgs1.googlecode.com/files/i386.2.6.29-rt2.ftrace.config-invain-invain.20090402)
for example,
At first,I built linux-2.6.29.rt2 kernel source.
And then,  I tested
kernel booting with this same kernel
binary(ex:vmlinuz,Systemmap,initrd , /lib/modules/2.6.29.rt2) on other
distros.

I will test with the same kernel binary on Q8200 /Q9300(Core2Quad)
using ubuntu 8.04 without fedora 9 later on.

Ok, can you try the following ? Boot into fedora, copy the fedora
config file into your -rt build directory and enable preempt-rt on
it. Now build the kernel and install it with "make modules_install
install". Does this work ?

Thanks,

FYI, I'm running a few Fedora "10" systems (not exactly the
same as GeunSik's) with preempt-rt kernels (2.6.29-rc8-rt3
to 2.6.29-rt2, and I'll test 2.6.29.1-rt4 soon), but I've
never experienced such a trouble with them.

[GeunSik Lim]

I tested with howto that you explained.
Sorry for my late response about your advice.
Specially, Thank you for presentation about CFS scheduler
at the 3rd korea technical jamboree last year.

.
I compiled -rt kernel source with gcc 4 on fedora 9 distribution
directly as you said.
I  boot -rt kernel binary on fedora 9 distribution successfully about
Q9300 target.

But, I still can't boot -rt kernel binary on fedora 9 about Q8200 target.
I will report tomorrow that I capture kernel error display with my
digital camera.

This is a summary report until now.

Below is test result about Quad CPU Q8200.
When I boot with linux-2.6.29-rt2 on Intel Core2 Quad CPU Q8200, I
still meet below error.
