[Xenomai-help] Dual Xeon 2.6.13 SMP config problem

[Xenomai-help] Dual Xeon 2.6.13 SMP config problem

[Nathaniel Villaume]

Hi all,

This email might be slightly off-topic because it's related to getting 
even a vanilla SMP kernel running (even though I can get the UP version 
to run Xenomai).

I performed two tests:

My distro is FC3 with linux-2.6.9. I'm trying to get the SMP version of 
2.6.13 running with Xenomai.

Test #1:
========
Use my distro's smp kernel (which boots) config to build the 2.6.13 
kernel. 
I ran make oldconfig, then make menuconfig, and turned off Experimental 
options.
I can't boot:  mount complains: "mount: error 6 mounting ext3"... etc.

Test #2
==========
I used the single CPU kernel config to build the adeos-patched 2.6.13 
kernel.  This boots and xeno latency runs fine. I had  a problem with 
`make devices` not making the devices, but I moved on to getting the SMP 
working.
If I switch to SMP in the kernel config, the machine doesn't boot.  
Instead, it complains: "mount: error 6 mounting ext3".
I checked that the ext3 is being compiled as a module.... I literally 
only change the SMP option.

I found some things on the internet about the ext3 error meaning that 
the driver wasn't compiled into the kernel.  I tried this, even though 
it shouldn't matter.  It doesn't work. I get more details about the 
kernel panic:
EIP is at kmem_cache_create

Looks like the trace/stack is:
mb_cache_create
init_ext3_xattr
init_ext3_fs
sys_init_module
sysenter_past_esp

"/bin/lvm exited abnormally."

I feel like I must be missing something obvious, any ideas?  Would my 
configs be of use?  I've looked through side-by-side diffs and can't see 
meaningful differences. I saw something about udev --which might explain 
my inabilty to create /dev/rtp0 with 'make devices'

I'd appreciate any pointers to what might be wrong,
-Nate

Why not use 2.6.15 immediately ?

Are there any other errors before that one ?

Hi, 
It turns out that I had to upgrade the mkinitrd package. The one that comes with FC3 doesn't build the image correctly for SMP.  That said, I now can build and boot a vanilla 2.6.15 kernel, but when I try to boot the ipipe-patched kernel, I get the following error near the end of the boot-sequence: (  I thought it was an X-server problem it comes so late, but then I booted to init level 3, and I get the same thing)

hda: dma_timer_expiry  dma_status == 0x24
hda: dma: int recovery 
hda: lost interrupt

Then the kernel hangs. (Num Lock key doesn't make the lights blink.)

The configs have two differences: (seriously) 
1) The dates are different, 
2) ipipe is included in the failing kernel. 

I would like to know if there are any other tests I can do to isolate the cause of this failure. 

I appreciate any comments, 

Nate

Please send me the .config privately.

Hi...
I thought I was going to have to eat my words this morning when my 
system booted perfectly  (run level 3), multiple times.   I still don't 
know what changed. To be clear, I no longer see the "hda: interrupt 
lost"  error.

Nevertheless, my computer still hangs when I start X, or when I try and 
compile xenomai (from the basic terminal, without X)
 It's a strange type of hang because I can get other terminals 
(Ctrl-Alt-F2, etc.), but then the login hangs after entering my passwd.  
When I Ctrl-C the build, I got a message from make, but then the prompt 
never returned. Numlock key toggles the keyboard light.

Philippe, I'm sending you my config separately.

Please advise. Thanks,

-Nate

Ok. Are you running 2.6.13? If so, which Adeos release is used?
