During the recent testing on the linux-4.19.89-ipipe-9-xenomai-3.1 (linux-4.19.89, ipipe-core-4.19.89-x86-9.patch, xenomai 3.1),
the kernel outputs some exception messages, as follows.
Please give me some hints!
Thanks a lot.

Are you using the perf tool here?
Also, can you check if the issue persists with a recent dovetail kernel
(5.15 or 5.10)? Or are you locked into these versions technically?

Hi Jan,
This is the only kernel version. Besides, these problems are hard to reproduce.
Whether some configurations related to perf are enabled in the kernel？
The following are the configuration items for perf:
CONFIG_CGROUP_PERF=y
CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE=y
CONFIG_HAVE_PERF_EVENTS=y
# Kernel Performance Events And Counters
CONFIG_PERF_EVENTS=y
# CONFIG_DEBUG_PERF_USE_VMALLOC is not set
# Performance monitoring
CONFIG_PERF_EVENTS_INTEL_UNCORE=m
CONFIG_PERF_EVENTS_INTEL_RAPL=m
CONFIG_PERF_EVENTS_INTEL_CSTATE=m
# CONFIG_PERF_EVENTS_AMD_POWER is not set
# CONFIG_PCIEASPM_PERFORMANCE is not set
CONFIG_HAVE_PERF_EVENTS_NMI=y
CONFIG_HAVE_HARDLOCKUP_DETECTOR_PERF=y
CONFIG_HAVE_PERF_REGS=y
CONFIG_HAVE_PERF_USER_STACK_DUMP=y
CONFIG_CLS_U32_PERF=y
# CONFIG_DEVFREQ_GOV_PERFORMANCE is not set
# Performance monitor support
CONFIG_HARDLOCKUP_DETECTOR_PERF=y
# CONFIG_RCU_PERF_TEST is not set

No, I meant of you are calling "perf" in order to profile some
applications. The pure activation of the related kernel features is not
considered problematic, but some "perf" feature are if actively used.

If you do not need those features, you may also try disabling them, if
that changes the picture. Also compare your config in this regard to the
config we test in xenomai-images (just a reference, not as the only
possibly valid config, by far).

My application software does not use perf.
I update the dual kernel after installing Debian 10.3,
install the xenomai cobalt library, and then run my application software.
How can I determine whether other applications in the system use perf?
Are these kernel exceptions related to perf?

Where can I get the xenomai-images and the config?
In addition, the kernel has a lot of configuration items.
How can I determine which ones should be turned on and off?
Is there a detailed instruction manual?
Thanks.

Applications usually do not call those services directly - like you
don't start the debugger from a normal application.

The warnings start with perf, but I might have been too quick to shoot
at it. The real issue is definitely the page fault. You don't have a
stack backtrace for the first one?
Also note that your kernel is not just old /wrt to its base version
(4.19), it's also not using the latest I-pipe patch for that
(ipipe-core-4.19.252-cip78-x86-23).

The key switches are warned about. But that does not exclude that some
sleeping bug is only surfaced by turning on or off some feature that
others usually do not touch.

No, these are the last messages that the kernel outputs.
The second exception is the same as the first one？
The logs are printed with "BUG: unable to handle kernel painting request at 00000000000a22e8"
>Also note that your kernel is not just old /wrt to its base version

What is the difference between cip and no cip on ipipe core?

How to further determine what caused it?
Thanks.

The issue is that you generally cannot trust succeeding BUG messages
after the first one. They may point into the wrong direction, not to the
root cause.

At some point, we moved from 4.19-LTS to 4.19-CIP as baseline for the
I-pipe patches as the latter kernel will live longer (10 instead of 6
years). No further development was done on the 4.19-LTS branch you are
sitting on, which is also missing some bug fixes to I-pipe since then.

Hard to say yet. Please re-try with the latest 4.19-ipipe release if
possible and also check if something changes positively when you use the
config from xenomai-images.

Hi，
Install the debian11.0 operating system on the machine.，the system can start normally.
But the system is abnormal after using this kernel,linux-5.4.133-ipipe-6-xenomai-3.1.1-20221216 (linux-5.4.133, ipipe-core-5.4.133-x86-6.patch, xenomai 3.1.1),
See the attachment for output information during kernel startup, and the kernel outputs some exception messages, as follows.
Please give me some hints!
Thanks a lot.

Linux is failing while trying to initialize the IRQ controler (APIC) of
your application processors (APs) (= non boot CPUs). There seems to be
a mismatch regarding LAPIC IDs.
Such IDs are normally extracted from the APIC ACPI table. Something
seems to go wrong there (taken from your attachment):
[ 0.214734] ACPI: x2apic entry ignored
There are a lot of such lines. This makes me wonder if your ACPI tables
are set up properly (which might be a BIOS/Firmware issue). That's
nothing Xenomai/ipipe specific. Does a standard Linux 5.4 boot on that
machine?
[ 0.214840] smpboot: Boot CPU (id 255) not listed by BIOS
That points into the same direction. Your boot CPU has a APIC ID of
255, I would expect 0.
[ 0.284534] setup_percpu: NR_CPUS:512 nr_cpumask_bits:512 nr_cpu_ids:1 nr_node_ids:1
nr_cpu_ids: 1 is strage. According to the line below we are on a NUMA
system (with one node) and I would expect a higher number of CPUs on
that system. So something is hiding your cores. (At least there is no
maxcpus=1 on your kernel cmdline).
NUMA configuration:
[ 0.008196] NUMA: Node 0 [mem 0x00000000-0x7fffffff] + [mem 0x100000000-0x207fffffff] -> [mem 0x00000000-0x207fffffff]
Hope that helps,
Florian

Linux is failing while trying to initialize the IRQ controler (APIC) of
your application processors (APs) (= non boot CPUs). There seems to be
a mismatch regarding LAPIC IDs.
Such IDs are normally extracted from the APIC ACPI table. Something
seems to go wrong there (taken from your attachment):
[ 0.214734] ACPI: x2apic entry ignored
There are a lot of such lines. This makes me wonder if your ACPI tables
are set up properly (which might be a BIOS/Firmware issue). That's
nothing Xenomai/ipipe specific. Does a standard Linux 5.4 boot on that
machine?
[ 0.214840] smpboot: Boot CPU (id 255) not listed by BIOS
That points into the same direction. Your boot CPU has a APIC ID of
255, I would expect 0.
[ 0.284534] setup_percpu: NR_CPUS:512 nr_cpumask_bits:512 nr_cpu_ids:1 nr_node_ids:1
nr_cpu_ids: 1 is strage. According to the line below we are on a NUMA
system (with one node) and I would expect a higher number of CPUs on
that system. So something is hiding your cores. (At least there is no
maxcpus=1 on your kernel cmdline).
NUMA configuration:
[ 0.008196] NUMA: Node 0 [mem 0x00000000-0x7fffffff] + [mem 0x100000000-0x207fffffff] -> [mem 0x00000000-0x207fffffff]
Hope that helps,
Florian
