hi,
i'm trying to use ingo's 2.6.15-rt16 patch on an x86_64 machine but it
keeps crashing in kmem_cache_init during bootup. i've tried older
2.6.15-rtX patches and they all crash during startup but vanilla 2.6.15
works fine for me. anyone else seen this happen with realtime-preempt
patches? here's the message:
Bootdata ok (command line is ro root=LABEL=/ console=ttyS0,9600)

The -rt patch currently doesn't support NUMA. Please turn in off for
now (do you really need it?).

I'm betting this is the same thing I'm seeing. Are you running on a
uniprocessor x86_64? And if so are you seeing messages similar to the
following?
init[1]: segfault at ffffffff8010fadc rip ffffffff8010fadc rsp
00007fffffdacfc8
If so, then I suspect that you're getting a segfault in ld.so (at least
that's the furthest I've gotten so far). Something about how the kernel
sets up the memory map is upsetting dynamically loaded executables. I
can boot with init=/sbin/sash, but when I try and run a dynamically
linked program, I get segfaults.
You might try turning off LATENCY_TRACING and see if that allows you to
boot and run (works for me).
Meanwhile, I'm going to try and pin this down to something better than
"somewhere in ld.so..."

hi,
actually i'm running on a dual processor x86_64. with the problem i was
having, i never got far enough to see the message you asked about. Steven
Rostedt's suggestion to turn off NUMA worked and i am now able to boot.
However, if I turn LATENCY_TRACING on, i get an immediate reboot after the
kernel is uncompressed. this doesn't sound like the same problem you're
having, though.

Man, I saw that LATENCY_TRACING and completely missed the NUMA
parameter. Sorry about that...
I must be the only person running a uniprocessor x86_64 that's working
with the -rt patches and trying to trace latencies. If I turn off
LATENCY_TRACING, I boot just fine.
Are you getting any output from the kernel before the reboot?

I'm still curious to what's happening with your kernel. I'm currently
running my x86_64 (typing right now on it) with CONFIG_SMP=n and
CONFIG_LATENCY=y. I know you probably sent a config before, but could
you send it to me again. (probably best to send it to me off list)
Thanks,

yeah, it's been gnawing at me too. Not really stopping me, but I've seen
it happen on two Athlon64's (3000+ and 3400+).
I'll send the .config offlist.

Another thing to try is the broken out latency tracing patch, maybe the
bug is somewhere else in -rt:
http://people.redhat.com/mingo/latency-tracing-patches/latency-tracing-patches-2.6.15-rc7.tar.gz
This applies to 2.6.15 final and can easily be applied to 2.6.16-rc1.

Clark,
Could you make sure that your modules in the initrd that you use are the
ones created with the LATENCY_TRACE option. After converting all the
modules into compiled in options, I successfully booted the kernel. So
you might have an incompatibility with the modules in initrd, when you
turn on LATENCY_TRACE.

Did you ever duplicated the failure?
I'm fairly certain that the initrd contains the appropriate modules,
since I regenerate the initrd each time I generate a new kernel, but
I'll go back and verify.
I'll also convert modules to compiled in and see if that makes a
difference.

No, but I don't use an initrd, so my failure was first that it couldn't
recognize my harddrives. So I compiled in the necessary drivers into my
kernel, and it booted right up to the GDM login. I logged in, and was
going to reply to you, but I guess I have a different network card since
I had no network.

Thanks, I've been burnt before with incompatible modules in initrd, that
I now only use compiled in modules that are needed to boot (ide, ext3,
etc). When compiling 3 different kernels with several different configs
constantly for the same machine, it just becomes easier to not use an
initrd.

Ok, I took the config file I sent you, globally substituted '=y' for
'=m' and rebuilt, then booted that kernel. Other than a message that it
was unable to open the console (udev wasn't started) I got the exact
same failure (same panic backtrace).

One of the things I wanted to see was how the -rt patch worked with
SELinux, so I decided to try and run a kernel that looked like a distro
kernel (in this case FC4). I just put together some scripting logic to
build the kernel and module tree three times (athlon64, p3smp, and
duron). After I've rebuilt, I install on each target system using a
shell script that deletes the old module tree, rsyncs a new one,
installs the matching kernel and builds a new initrd.
Hmmm, FC4 is based on 2.6.14.x. Did something change in the 2.6.15
series that needs a user-space change as well? (I'm running a current
FC4 rootfs).

But, didn't you say that if you turn off LATENCY_TRACING that the -rt
patched kernel boots?
So, now it seems to be something hardware specific that is different
between your machine and mine.
Note: I'm using Debian.

Could you find where that ffffffff8010fadc is. Compile with debug info,

Gah. I'm an idiot. I wrote that last night as I was about to leave, then
just before going to bed I realized that it couldn't be a user-space
issue, since other kernel's work just fine. Put it down to
frustration :)

Yeah, I suspect so. I still have a nagging suspicion that something
about how memory has been setup is confusing ld.so while it tries to map
in the various sections of a dynamically linked executable.
Hmmm, it just occurred to me that it might be while ld.so is mapping in
dependent libraries, not while mapping file sections. Think I'll go poke
at that a little.

If the panic backtrace is to be believed, that's the address of mcount
(arch/x86_64/kernel/entry.S).
The code 0x15 at the end of the segfault message means (according to the
comment in fault.c) that the segfault is the result of a user-mode
protection fault while reading the address ffffffff8010fadc.
