Here [1] it says "Acoustics – Idle 2.5/2.6 Bel, Performance
Seek 2.8/2.9 Bel"

So what does that mean, the maximum is 2.9 Bel or 0.29 dB?

if so 4/5 fans are: 14.9, 15.9 (2), 14.7 dB(A)

and the HDD is: 0.29 dB

What material would that be?

The HDD is below with the PSU, I think.

I got an idea, aren't the noise specified by the manufacturer?

Here it says "Low-noise operation of up to 14.9dB(A)",
that's for the Shadow Wings 2 140mm PWM.


The CPU fans are "Low-noise operation of up to 15.9dB(A)", the
Shadow Wings 2 120mm PWM.


And the non-PWM Shadow Wings 2 140mm is
"Low-noise operation of up to 14.7dB(A)"


So that's 4/5 fans accounted for, I have to restart the
computer to see exactly what fan the remaining is. Anyway

db(A): 14.9, 15.9 (2), 14.7

How is it with db(A), if you have x db(A) from one thing, and
you have two of these, does that mean you perceive that as
2x db(A)?

Could you report this to Debian's Xen team as a bug? Perhaps it is
as simple as needing different kernel options in the netinst
installer kernel given that the full install works under HVM?

The Debian Xen team is very under-resourced for human help and it
has been a long time since they have managed to keep the version in
stable to a recent and supported one upstream. If you run a Xen dom0
on Debian I think really you need to be building your own packages
or using the Debian Xen team's packages from sid.

The stable packaged 4.11 hypervisor is out of even security support
upstream so it's not really suitable for production use. I don't
think the Debian Xen team would recommend using it but would instead
suggest using their newer package that;s in sid (on stable) and
test/report bigs against that. But let's get this reported.

I'm not skilled enough in Debian package building to help the team
but I do still report bigs sometimes; for production use I am
building packages from newer upstream source.

For this problem I can't help as I don't run HVM guests (only PV and
PVH).

I just discovered this already has been reported as a bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=983357

I don't know when an official fix will come , but I have come up with
a workaround that works for me:

This fix might also work on the live ISO images that are also reported
to crash and reboot in Xen HVM domUs.

Prerequisites: xorriso and initramfs-tools packages installed

Download/copy debian-11.0.0-amd64-netinst.iso into current working 
directory:


Step 1: Mount the original iso:

mkdir CD
sudo mount -o ro -t iso9660 debian-11.0.0-amd64-netinst.iso CD

Step 2: Copy the initrd.gz file we need to modify:

cp -p CD/install.amd/initrd.gz .

Step 4: Unmount the original iso:

sudo umount CD

Step 5: As root, extract the initramfs into a working directory:

sudo unmkinitramfs initrd.gz initramfs

Step 6: As root, edit the start-udev script that causes the crash and 
reboot:


sudo vi initramfs/lib/debian-installer/start-udev

In the start-udev script change this line:

udevadm trigger --action=add

to

dmesg | grep DMI: | grep 'Xen HVM domU' || udevadm trigger --action=add

and save the file

This change should only disable the udevadm trigger in Xen HVM DomUs.

Step 7: Re-pack the initrd into a new initrd file:

cd initramfs

find . | sort | sudo cpio --reproducible --quiet -o -H newc > ../newinitrd

cd ..

gzip -v9f newinitrd

Step 8: Create the new installation ISO:

cp -p debian-11.0.0-amd64-netinst.iso debian-11.0.0-amd64-xenhvm-netinst.iso

xorriso -dev debian-11.0.0-amd64-xenhvm-netinst.iso -boot_image any keep \
-map newinitrd.gz /install.amd/initrd.gz

Optional Step 9: Clean up

sudo rm -r initramfs newinitrd.gz initrd.gz

The ISO image debian-11.0.0-amd64-xenhvm-netinst.iso can now be used to 
install
Debian bullseye in a Xen HVM Domu. On the main menu, choose the Install 
option,

not the graphical or expert options, in order to boot using the modified
initrd.gz ramdisk.

Chuck Zmudzinski

https://en.wikipedia.org/wiki/Bel_(unit)


Doubling the sound energy adds 3 db.  So, the two loudest fans are 
around 19 dB.



The HDD is 2.9 Bel = 29 dB.


Beyond the fan acoustic noise, there is HDD vibration.  If you mount a 
HDD directly to a piece of sheet metal, the sheet metal will act like a 
sounding board and convert the HDD vibrations into sound.  My Antec 
Sonata chassis has silicon grommets and shoulder screws for mounting 
each HDD into its sled.  This design effectively decouples HDD 
vibrations from the rest of the case.  If you could implement the same 
idea for your HDD or for the drive cage, that would be good. 
Alternatively, you could put vibration dampers between bolted 
connections and/or damp the chassis vibrations.  Applying sound 
absorbing pads to the inside of the case should address both sound and 
vibration.

For a CPU with N cores (N=4 for an AMD Ryzen 3 3200G?) and an otherwise 
unloaded system, your test procedure should be something like:


   loop over governor choices
 set governor
  loop 3 times
sleep 60 seconds
print statistics
  endloop
 loop from 1 to N
   start background process
   loop 10 times
 sleep 6 seconds
 print statistics
   endloop
 endloop
 kill all background processes
   endloop


"print statistics" should include time, governor setting, number of 
background processes running, and CPU temperature.  If would be nice to 
also include system loading percent, CPU frequency, and CPU fan speed.

With the 'powersave' governor and all 5 fans "Silent", the CPU

Yes, but I know already that even with all fans (2*CPU cooling
tower, 3*case) at "Silent" and with the powersave governor it
still - if indeed anything changed - it still makes to much
noise so I still hibernate the computer when I don't use it.

The GPU fan looks so small it can't make a lot of noise one
would think, and the fans for the power supply/the HDD are
inside a little box even inside the computer case (don't know
if it has a name?) but if they are really noisy I guess it
could happen?

The case fans look like they would produce a lot of wind if really

That perforated metal plate at the bottom looks suspicious.

The underside of the chassis top could be covered with sound absorbing

A bit more adventurous is to run the CPU without fan for a few seconds.

Unplugging the chassis fans would make it easier to focus on the CPU 
fans, but all the fans should be operating with the chassis closed 
before applying any significant load.  (Or, at least the CPU fans, an 
open chassis, and a good floor fan.)



With my Intel motherboards, if I power up and the CPU fan is unplugged 
or not rotating (e.g. blocked by wires), the firmware will detect this 
during POST and halt the CPU.

You will not notice a change in CPU fan temperature or speed profiles as 
a function of the Linux governor setting until the motherboard CPU fan 
speed control is working and you change the CPU load.



Here is a Perl one-liner that should peg one core:

$ perl -e "1 while 1"


Press Ctrl+C to stop it.  Open multiple terminals an invoke the same to 
peg more cores.

Whatever interests you -- chipset, voltage regulators, memory modules, 
etc..  Because the instrument is hand-held, the challenge will be 
measuring the same spot at the same distance and same angle every time.

Changing the Linux CPU governor should affect the CPU frequency profile 
as a function of CPU load.  I use the Xfce panel applet "CPU Frequency 
Monitor" to monitor the CPU frequency and the "CPU Graph" applet to 
monitor loading of each core.

On my Intel desktop and server motherboards, CPU fan speed control only 
works with Intel CPU fans.  Aftermarket fans run at full speed all the 
time.  Try your AMD CPU fan.



Get a 3-pin and/or 4-pin fan speed controller and test the fans:

https://www.amazon.com/Zalman-Fan-Speed-Controller-FANMATE-2/dp/B000292DO0/

https://www.amazon.com/Noctua-NA-FC1-4-pin-PWM-Controller/dp/B072M2HKSN/


While STFW, I found a what might be a replacement for your external fan:

https://www.amazon.com/Wathai-Controller-Receiver-Playstation-Component/dp/B07VYGQPCZ/


The video card and power supply fans should have automatic fan speed 
control.  The video card manufacturer might offer a firmware or software 
utility for tuning the fan speed control profile.  A gamer power supply 
might have such a feature.  That said, I expect the factor defaults 
should be good enough for now.  I would leave them alone, unless you 
definitely hear too much noise coming from one or both.



Small fans at high RPM can be very shrill -- e.g. the spectra has a lot 
of high frequency energy.  I use 3.5" HDD mobile racks with two 30mm 
fans each (StarTech DRW115SAT).  When I install four in a computer, it 
sounds like a B-52!

Is the message saying that the device's are too slow being that they're
probably USB v2? It doesn't make sense that an AMD Ryzen CPU with 32 Gb

Hi,

Emanuel Berg photographed:

The case fans look like they would produce a lot of wind if really
running at full speed. Whatever, i'd make a closer photo, unplug them,
listen how much noise is missing, and then plug them in again guided by
the photo.

That perforated metal plate at the bottom looks suspicious.
Power supply and hard disk cage, if i remember correctly ?
How is the noise if you unplug the power of the whole mainboard ?


Have a nice day :)

If nothing else helps to find the culprit, then consider to unplug all
case fans to prove that it's not them.
A bit more adventurous is to run the CPU without fan for a few seconds.

(I assume from your fan list that it is a larger box where such
manipulations are feasible.)

Not specifically for computer fans, and the controller electronics
(which is a must for a BLDC) has to be somewhat prepared to do this,
but here [1] is a blog post which gives a rough idea of the things
involved.

BLDCs are a huge thing in drones and things.

This will result in a quite short run of xorriso, which will report
something like

   ISO image produced: 8108 sectors
   Written to medium : 8288 sectors at LBA 193024
   Writing to 'test.iso' completed successfully.

(The numbers 8108 and 8288 are result of the sizes of the two dummy 
files

which i used as $new_kernel #and new_initrd. Yours will be substantially
larger due to the typical size of an initrd.)

Inspection of the boot equipment of test.iso shows no differences,
except the new storage position of the El Torito boot catalog and the
enlarged ISO image size.

When mounted by Linux, the paths
   /mnt/iso/install.amd/xen/vmlinuz
   /mnt/iso/install.amd/xen/initrd.gz
lead to the content of $new_kernel and $new_initrd.

Then it depends on the inner doings of boot loader and starting system,
whether this perky change is tolerated.

Hi Thomas,

Thank you for these tips. I will use them to try to get a bullseye
Debian installer ISO working in a Xen HVM DomU next week
when I have some spare time and post the results here.

All the best,

Chuck



This approach (using xorriso with -dev, -boot_image, and -map options)
works to change the kernel and ramdisk on the ISO, and the new
ISO does boot into a Xen HVM without crashing and rebooting, but I
still have not succeeded in getiing the ramdisk configured correctly to
boot the Debian installer. Using the ramdisk of a full install on the
ISO causes init to drop to an initramfs shell because that ramdisk
is not configured to start the Debian installer but instead expects a
root filesystem to be passed to it on the linux kernel command line.

I expect it is possible to create a ramdisk that will successfully boot
the Debian installer in a Xen HVM. I think some components from
the ramdisk of a full install are needed to prevent the crash and
reboot, and it is a matter of identifying what components from
the ramdisk of a full install are needed. I would suspect some
kernel module that a Xen HVM needs is missing from the ramdisks
on the installation ISO.

I will continue to work on it this week in my spare time.

Cheers,

Chuck

Jigdo is not suitable for making changes to the ISO which it reconstructs.
(It is rather suitable for reducing the download effort with ISOs which
are slightly changed towards an ISO which you already have.
See the question "Files to scan:" of program jigdo-lite.)

If you have files which you want to add to the ISO or if you want to
replace existing files of the ISO, then maybe
  https://lists.debian.org/debian-user/2021/08/msg01170.html
is of help, where i propose how to override a kernel and an initrd in the
ISO.
As mentioned in that post, there is the possibility that checksum lists
or certficates let the booting system detect that existing files were
altered. Your mileage may vary.

I can only answer the last of your questions: If you want to add a custom  
mirror during the install, go to the top of the menu and choose
"enter information manually". The installer will then ask you for the host  
name, path and proxy information of your custom mirror.


Scroll near the end of
https://masysma.lima-city.de/37/debian_i386_installation_reports_att/m6-d11a3-i386-netinst.xhtml
for screenshots of the respective dialogs. It is from an an alpha release of  
the installer but the dialogs should not differ too much from the final one.

Thanks, I tried the textual install, so yes the first option to manual

must have missed it in the graphical install.

Anyway, as for changing the list, I suspect unlikely the list comes from

surely the installation will WRITE the sources.list based on your selection.

I would not bother with under-the-hood manipulations: install the task-

This will not convert the user environment to korean but instead bring
him the possibility to display and type korean inside his english

Then your user will be able by himself to click on an applet or a menu

Audio device got stuck!

[The Wanderer]

I just dist-upgraded against testing, and after the upgrade, MPlayer
started to report

> Audio device got stuck!

over and over again (about once or twice a second, I think) during
playback of any file with audio, while not actually producing any
audible sound.

The solution to this turns out to be to kill (and, thus, implicitly
restart) the user-specific PulseAudio daemon:

$ pulseaudio --kill

With that done, MPlayer works fine again. (What I found in searching the
Web for the solution seems to indicate that other audio-using programs
would have had the same problem.)


What puzzles me is that none of the packages I saw listed for the
upgrade which triggered this seem related to PulseAudio, either directly
or in any obvious indirect way.

I'd like to figure out which package(s) were involved, so I can know
what packages I may need to do this again for future upgrades of.
However, I'm not managing to think of any reasonable way to identify
them.

Can anyone suggest a reasonable way to identify the full stack of
packages which pulseaudio (or, for that matter, any designated package)
depends on, either directly or indirectly?

It wasn't me, but an apparent breakage.

What do you mean by "when the dust has settled" in this context?

Bonjour la liste

A la maison (de geek) j'ai plusieurs ordinateurs -tous sous Linux,
mais
pas forcément Debian-  et surtout de l'Ethernet (le wifi sert
occasionnellement, surtout pour les tablettes).

J'ai un serveur (de récupération, c'était un déchet d'une boite
d'avocats) sous Debian testing avec deux interfaces réseaux:

Voici la sortie de ifconfig pour les deux interfaces réseaux:

eno1: flags=4163  mtu 1500
 inet 192.168.2.2  netmask 255.255.255.0  broadcast
192.168.2.255
 inet6 2a01:e0a:3d0:7b50:9e8e:99ff:fe64:fcc2 prefixlen 64
scopeid 0x0
 inet6 fe80::9e8e:99ff:fe64:fcc2  prefixlen 64 scopeid
0x20
 ether 9c:8e:99:64:fc:c2  txqueuelen 1000  (Ethernet)
 RX packets 3892  bytes 378141 (369.2 KiB)
 RX errors 0  dropped 0  overruns 0  frame 0
 TX packets 192  bytes 19267 (18.8 KiB)
 TX errors 0  dropped 0 overruns 0  carrier 0 collisions 0
 device interrupt 16

eno2: flags=4163  mtu 1500
 inet 192.168.1.20  netmask 255.255.255.0  broadcast
192.168.1.255
 inet6 fe80::9e8e:99ff:fe64:fcc3  prefixlen 64 scopeid
0x20
 ether 9c:8e:99:64:fc:c3  txqueuelen 1000  (Ethernet)
 RX packets 113  bytes 13209 (12.8 KiB)
 RX errors 0  dropped 0  overruns 0  frame 0
 TX packets 107  bytes 10837 (10.5 KiB)
 TX errors 0  dropped 0 overruns 0  carrier 0 collisions 0
 device interrupt 17

Où 192.168.2.x contient le modem Fibre-optique Free, et
192.168.1.y est
un réseau local (avec l'imprimante dessus), et un PC interne (en
ethernet) dans le cabinet de mon épouse (psychologue)


Comment configurer le routage?

J'ai l'impression que la commande route est obsolète

Librement.
