No, this is not necessarily a kernel bug. It can be a hardware bug and it
is plausible it can not be solved with a driver work-around.

You are hitting a problem and you want someone else to fix it for you. The
answer may simply be that you need to replace the NIC with something else.

FWIW, I have these Intel NICs in my two NUCs and they are functioning
fine. With Debian 12.5 and the latest updates.

$ lspci -v -s 00:1f.6
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection I219-V (rev 
21)
DeviceName:  LAN
Subsystem: Intel Corporation Ethernet Connection I219-V
Flags: bus master, fast devsel, latency 0, IRQ 123, IOMMU group 7
Memory at df10 (32-bit, non-prefetchable) [size=128K]
Capabilities: 
Kernel driver in use: e1000e
Kernel modules: e1000e

The revision of the NIC may determine whether you have *hardware* problems
or not.

> This needs to be fixed!

Quick answer: replace the NIC. And do some groundwork to determine if the
NIC you replace it with has issues you should be aware of or not.

> I have already tried disabling the offloads and it does
> not work.

The specific offloads seemed to be the CRC related ones.

# ethtool -k eno1
Features for eno1:
rx-checksumming: on
tx-checksumming: on
tx-checksum-ipv4: off [fixed]
tx-checksum-ip-generic: on
tx-checksum-ipv6: off [fixed]
tx-checksum-fcoe-crc: off [fixed]
tx-checksum-sctp: off [fixed]

Note: when you disable these, throughput can drop sharply.

The other setting suggested was to hike the TX ringbuffer.

# ethtool -g eno1
Ring parameters for eno1:
Pre-set maximums:
RX: 4096
RX Mini:n/a
RX Jumbo:   n/a
TX: 4096
Current hardware settings:
RX: 256
RX Mini:n/a
RX Jumbo:   n/a
TX: 256
RX Buf Len: n/a
CQE Size:   n/a
TX Push:off
TCP data split: n/a

# ethtool -G eno1 tx 2048 rx 2048
# ethtool -g eno1
Ring parameters for eno1:
Pre-set maximums:
RX: 4096
RX Mini:n/a
RX Jumbo:   n/a
TX: 4096
Current hardware settings:
RX: 2048
RX Mini:n/a
RX Jumbo:   n/a
TX: 2048
RX Buf Len: n/a
CQE Size:   n/a
TX Push:off
TCP data split: n/a

The reason the ringbuffers are important is that the kernel and the OS can
construct packets faster in bursts than the NIC can handle, so the OS can
queue up packets in the ringbuffer and the NIC can asynchronously pick the
packets from the buffer and send them across the wire. If the ringbuffers
are set too small, they will overflow and you will get overflow errors.

Excellent data-point, you have ruled out whether the cable is faulty or
not. But your assumption that this is the kernel module that is broken
is still faulty.

Provably, I am running the same type of NIC (albeit a different revision)
with the same driver and I do not observe any issues. Thus, leveraging

Do I need to set some more settings to ensure that the system will

Hi,

In the Linux kernel source are available two options to reboot on panic:

config BOOTPARAM_SOFTLOCKUP_PANIC
bool "Panic (Reboot) On Soft Lockups"
depends on SOFTLOCKUP_DETECTOR
help
  Say Y here to enable the kernel to panic on "soft lockups",
  which are bugs that cause the kernel to loop in kernel
  mode for more than 20 seconds (configurable using the 
watchdog_thresh

  sysctl), without giving other tasks a chance to run.

  The panic can be used in combination with panic_timeout,
  to cause the system to reboot automatically after a
  lockup has been detected. This feature is useful for
  high-availability systems that have uptime guarantees and
  where a lockup must be resolved ASAP.

  Say N if unsure.

and:

config BOOTPARAM_HARDLOCKUP_PANIC
bool "Panic (Reboot) On Hard Lockups"
depends on HARDLOCKUP_DETECTOR
help
  Say Y here to enable the kernel to panic on "hard lockups",
  which are bugs that cause the kernel to loop in kernel
  mode with interrupts disabled for more than 10 seconds 
(configurable

  using the watchdog_thresh sysctl).

  Say N if unsure.

from Documentation/admin-guide/kernel-parameters.txt you can set it as 
kernel parameter or via sysctls:


softlockup_panic=
[KNL] Should the soft-lockup detector generate 
panics.

Format: 0 | 1

A value of 1 instructs the soft-lockup detector
to panic the machine when a soft-lockup occurs. 
It is
also controlled by the kernel.softlockup_panic 
sysctl

and CONFIG_BOOTPARAM_SOFTLOCKUP_PANIC, which is the
respective build-time switch to that functionality.

and the same for "kernel.hardlockup_panic" that it seems it hasn't an 
help entry in the documentation file, I found it here:



nmi_watchdog=   [KNL,BUGS=X86] Debugging features for SMP kernels
Format: [panic,][nopanic,][num]
Valid num: 0 or 1
0 - turn hardlockup detector in nmi_watchdog off
1 - turn hardlockup detector in nmi_watchdog on
When panic is specified, panic when an NMI watchdog
timeout occurs (or 'nopanic' to not panic on an NMI
watchdog, if CONFIG_BOOTPARAM_HARDLOCKUP_PANIC 
is set)

To disable both hard and soft lockup detectors,
please see 'nowatchdog'.
This is useful when you use a panic=... timeout and
need the box quickly up again.

These settings can be accessed at runtime via
the nmi_watchdog and hardlockup_panic sysctls.

To learn more I suggest to install the "linux-source-6.1" package and 
investigate the "Watchdog" option, it is under "Device Drivers".
The BOOTPARAM_SOFTLOCKUP_PANIC and BOOTPARAM_HARDLOCKUP_PANIC options 
are under "Kernel hacking" → "Debug Oops, Lockups and Hangs".

What needs to happen, according to that analysis, is to close one of the
windows not by File -> Exit or File -> Quit, but by File -> Close. (In
my - severely obsolete - Thunderbird version, it's near the top of the
File menu, and has the associated keyboard shortcut Ctrl+W.)

Reportedly, after doing that, if you then quit the program entirely (by
any of the other available methods), when you re-launch it it will come
up with only one window.


Thank you, that fixed it!


The situation appears to be triggered by doing one of the UI actions
that causes Thunderbird to open a new "main" window - which can happen
by accident, e.g. by trying to detach a tab from the main Thunderbird
window (which apparently doesn't open a new window with just that tab,
but rather opens an entire new main Thunderbird window with the contents
of that tab active). That in turn can (I would expect) be done
accidentally by trying to drag a tab to a new position in the tab bar,
but unintentionally dropping it at a place which is instead treated as
outside of the window.

Thanks for actually reading the links for us -- I was too deep
in some ugly PHP code to do it myself ATM.

Makes sense, TB seems to remember its window configuration [1] when
closing, like its cousin but seems to remember "I had *two* windows
last time around", quite unlike its cousin.

Yo tenía una chuleta pero creo que no te va a servir porque ahora no se
instala por defecto la orden ifconfig. Además las redes públicas que he
visto en aeropuertos, etc.,  parece que no son demasiado estándar  y más
bien están pensadas para dar acceso a equipos con Windows, por eso lo de
que te pide el usuario desde el navegador, así que va a ser complicado
que puedas acceder desde consola. Te pongo  aquí la chuleta por si te sirve:



Hace falta el paquete wireless-tools y para redes con seguridad wpa el
paquete wpasupplicant.

Para detectar la tarjeta:
iwconfig

Para levantarla:
ifconfig wlan0 up

Para escanear redes:
iwlist wlan0 scan

Una vez sabemos el nombre de la red y su seguridad, escribimos en
/etc/network/interfaces:

iface wlan0 inet dhcp
#para redes abiertas y con seguridad wep indicamos el nombre de la red:
wireless-essid nombre_red
# para redes con seguridad wep indicamos su contraseña en ascii:
wireless-key s:clave_en_ascii
# para redes con seguridad wpa2 indicamos el nombre de la red y la clave
en ascii:
wpa-ssid nombre_red
wpa-psk clave_en_ascii
# comentar las líneas que no sean necesarias en cada caso, si no no
funciona.

ejecutamos ifup wlan0 y ya tenemos la red activa.
Comprobamos con iwconfig y con un ping www.gnu.org o con un navegador:
lynx www.gnu.org
Si queremos desactivar la red:
ifdown wlan0

Para redes abiertas y con seguridad wep también podemos prescindir de
ifup (que lee el fichero interfaces) y usar iwconfig (que es una
herramienta de más bajo nivel):
Para redes abiertas indicamos el nombre de la red:
iwconfig wlan0 essid nombre_red

Para redes con seguridad wep indicamos el nombre de la red y la clave:
iwconfig wlan0 essid nombre_red key s:clave

Posteriormente solicitamos una dirección IP:
dhclient wlan0

I see. An Internet enquiry into the multiple-window problem produces many hits,
some of them over a decade old.

The most recent I've found (Dec 2023), advises simply creating another

Actualización automática de cambios en los archivos

Pregunta de tanteo... 

¿Qué biblioteca / aplicación /sistema / método tenéis instalado /usáis 
en Debian para que la información de los archivos locales/remotos en 
red (p. ej., la hora de modificación)) se actualice automáticamente?

En mi sistema no lo hace, seguramente porque hago instalaciones del 
sistema sin activar los paquetes recomendados y/o sugeridos, pero esta 
funcionalidad me temo que es importante, aunque sólo se a afectos

Because it'd been off-topic, just as your little oblique stab here is ;-D

It would've been clearer to have advised using another mail application,
period, if the OP didn't trust Gmail. But the manner in which you
phrased your advice implied that Gmail was a "web application" that
didn't support IMAP, which is false, so I piped up (or is it in?) in my
admittedly somewhat oblique (to the matter at hand) manner.

But no harm, no foul, and all is well. The only real mystery is how
Tomas resisted getting yet another lick in against Gmail and Google, et
al.

One might argue that a driver's whole raison d'être /is/ to work around
hardware bugs. But then, perhaps I'm a cynic ;-)

You make it sound like it's a rare occurrence, but it's actually
quite common.  Most of it is discrete so you'll rarely be exposed to it,
but `grep bugs /proc/cpuinfo` is one of the places where you can see it
being somewhat documented.

Well, naturally. But if there is some setting which I _could_ set that
would get me closer to my desired state, I would still like to know
which one and perhaps even what might be an appropriate value for it.

No, unfortunately I do not have the gift of divination, it would be
convenient. I am saying that you cannot use software to protect yourself
entirely from software bugs.

You probably can. But first check if your VM has an emulated hardware
watchdog.

Are you saying that the settings themselves are reasonable for the
purpose, and that this particular crash just happened to be such a one
that no software running on the system in question can reasonably help
with that scenario?

This happened on a VM that I can't directly influence the hardware
configuration of (a commercially provided VPS), but I should be able
to jury-rig something using the provider's API if necessary.

If the crash was bad enough to freeze the kernel before it could
trigger the reboot, there is nothing the software can do.

You need a hardware watchdog. If your motherboard has one, just install
and enable the corresponding daemon, and check it works by SIGSTOPing
it.

If your motherboard does not have one, you can probably DIY one from a
RPi or an Arduino.

Automatic reboot on kernel crash in Debian 12 - how?

[Michael Kjörling]

I have a handful of Debian 12 systems that I want to configure such
that they reboot automatically in case of a problem. I have set them
up with userspace scripts (executed through cron) to reboot if
something goes wrong there; that appears to work as expected if I
induce an issue that those scripts check for. That leaves kernel-level
issues.

To try to configure this, I have created a file
/etc/sysctl.d/local.conf (owned by root:root, mode 0644).

# cat /etc/sysctl.d/local.conf
kernel.panic = 120
kernel.panic_on_oops = 1
kernel.panic_on_stackoverflow = 1
kernel.panic_on_io_nmi = 1
#

With the exception of panic_on_stackoverflow, as far as I can tell
these are in effect after a reboot:

#  sysctl kernel.panic kernel.panic_on_oops kernel.panic_on_stackoverflow 
kernel.panic_on_io_nmi
kernel.panic = 120
kernel.panic_on_oops = 1
sysctl: cannot stat /proc/sys/kernel/panic_on_stackoverflow: No such file or 
directory
kernel.panic_on_io_nmi = 1
#

However, this morning I woke up to one of those systems showing a
kernel crash dump and being frozen. Unfortunately the first part of
the crash dump had scrolled past so I couldn't tell what class of
problem caused the crash.

Do I need to set some more settings to ensure that the system will
automatically reboot on a panic? If so, what?

I know that best is to not crash; this is _in case of_.

digikam is a kde application, so you need the kde stuff at least for it.
I use it too, have less memory, and still have no delay problems.

Re: removed foreign architecture -- again

[fxkl47BF]

just a comment about this procedure
i shopped around the interweb before jumping in to this

apt purge `dpkg --get-selections |grep :i386 |awk '{print $1}'`
dpkg --remove-architecture i386

this what i settled on
but apt wanted to remove a passel of non-i386 packages that i really liked
and install a bunch of packages i really did not care for
apt seems to be using some sort of bizarre ai
it takes my input as a suggestion and does what hell it wants to

aptitude purge `dpkg --get-selections |grep :i386 |awk '{print $1}'`
did exactly what i needed
it only removed the i386 packages and left the rest alone
as a result i just removed the packages and rebooted

your mileage may vary
