have you inserted usb disk with firmware during installation?

[lsg]

installer seems very buggy

bullseye installer can't find firmware after i insert usb disk

after lots of frustration and effort, i realize i shall copy firmware to 
sda1, which use vfat FS, then installer can get firmware without 
prompting me.

installer search disk for iso file, can't find suitable one, and display 
"No kernel modules found" screen



does your installer find your iso file? or do you really install via 
http? network connection isn't needed if you use hard disk installation 
method, with debian-11.6.0-amd64-netinst.iso you can install bare 
minimal debian system

That wouldn't help. My method pulls the kernel and initrd from the iso
itself. I got the same error you did.

I used the weekly build, so I shall wait until the next build and see
if that works.

Really? i am afraid vmlinuz and initrd pair in iso file don't include 
program that search disk for iso file, as pair in hd-media directory does


Debian11.6/main/installer-amd64/current/images/hd-media

though it's possible to boot iso file with grub, but it's too complicated

it seems few users are using hard disk installation method theses days

There isn't much you can do about this. It is usually a temporary
issue thats happens after Linux kernel updates. The installer is
now out of step. It gets automatically fixed after some time.

Thanks! i've thought updating iso image and hard disk installer are 
automatic


it's very frustrating, i've never been so disappointed with debian

it will be easier if i can determine if they match by matching file name 
of iso file with that of vmlinuz and initrd pair (their file names shall 
all include same version number)


i have successfully used bullseye hard disk installation method for i386 
about one month ago, i don't know why it doesn't work this time

You shouldn't need separate vmlinuz and initrd.gz files. You should be
able to boot directly to the iso image. Depending on how talented your
computer's firmware is, you may have to copy the iso image to sdb, not
sdb1. E.g.:

dd if=.iso of=/dev/sdX

What instructions did you start with? Exact URL, please.

I've been playing with a separate partition to house a Debian installer
ISO should I ever need it for rescue or re-installation. But that
depends on having grub installed and a suitable entry for the d-i iso
image. If that's what you want to do, I can help with that also.


Thank Charles!

https://www.debian.org/releases/stable/amd64/ch04s04.en.html

to reproduce my problem, you need 3 files: vmlinuz, initrd.gz and 
corresponding iso file


add entry to grub menu, boot it to see if it can locate iso file, there 
is no need to re-partition your disk


my pc can boot usb stick, but during installation it prompts me for usb 
disk with non-free firmware , this step fails

hard disk installation method fails

[lsg]

this is quite unbelievable, it's most widely-used platform: amd64

installer says "No kernel modules found", probably due to kernel mismatch

debian-11.6.0-amd64-netinst.iso is at sdb1, vfat partition, i've checked 
it with sha256sum


vmlinuz and initrd.gz are copied from:

Re: failed to load rtl_bt/rtl8761b_fw.bin

[lsg]

Thank David! you are right, i get firmware for bookworm, extract it with 
dpkg-deb, copy it to /lib/firmware/rtl_bt, now bluetooth works in bullseye

failed to load rtl_bt/rtl8761b_fw.bin

[lsg]

i have usb wireless dongle, it uses rtl8761b chip, it works in opensuse

but bullseye complains though i have installed non-free firmware-realtek:

[   16.123855] bluetooth hci0: firmware: failed to load 
rtl_bt/rtl8761b_fw.bin (-2)

bullseye installer can't load non-free firmware from usb stick

[lsg]

but i use hard disk installation method, i put firmware in same place as 
iso image, installer can locate firmware without prompting me

Re: why rfkill not list my wifi device

Interesting. Running "modprobe rfkill" wouldn't return anything because
the module is already installed. However, I get a slightly different
result from the lsmod command:

root@jhegaala:~# lsmod | grep rfkill
rfkill 32768  7 bluetooth,thinkpad_acpi,cfg80211

The rfkill module is used by three other modules in my case. The first
two are related to bluetooth. The third, which your listing also shows,
controls network interfaces, including wifi. So I conjecture that you
have all the right modules installed.

However, in my reading I found out that not all wifi drivers support
rfkill. That may be your problem.


Thank Charles ! you are right. i have 2 usb wifi adapters now, one can 
be listed by rfkill, the other can't

actually i want to use rfkill to block or unblock device

is it possible to do it with wireless-tools?

In that case check if "rfkill" kernel module is actually loaded, 
because it is necessary for rfkill utility to function:

    $ lsmod | grep -iE "rfkill"

Use "modprobe" utulity to load it:
    $ sudo modprobe rfkill

It is possible that driver module (your current version) for this 
adapter simply doesn't support "rfkill" subsystem.

Thank Alexander! i run lsmod | grep -iE "rfkill", it says

rfkill 20480  2 cfg80211

both "modprobe rfkill" and rfkill return nothing

For this adapter, according to Wireless Wiki [1], you should use 
universal driver "rtl8xxxu". See if it was loaded:

    $ sudo lsusb -t

Check out the logs for relevant messages:
    $ sudo grep -iE "rtl|firmware" /var/log/syslog

This should give you a hint about a firmware file needed for this adapter.
Probably it is a good idea in general to install firmware package for 
Realtek-based devices from "non-free" section of Debian repos:

    $ sudo apt install firmware-realtek

Re: why some memory are missing

I'm pretty sure it can address 2^32 bit aka 4 GB. But within this

physical main memory within the 2^32 bit range.


Typically Chipsets/BIOS can map the missing memory somewhere above 4 
GB but not every Chipset/BIOS does this. Then even in 64 Bit mode 
you'll lose memory in the range of the PCI address space. If, on the 
other side, the Chipset/BIOS maps those memory regions above 4 GB then 
even in 32 Bit Mode Linux can use this memory (via PAE).

Thank hede! you solved my problem! i enable Memory hole Remapping in

i've tried bullseye for amd64, it doesn't help

why some memory are missing

[lsg]

i have hp dx5150, running buster

bios shows 4G memory, but in buster, top shows 3282.8M

i have independent graphics card, memory isn't shared i think

i have tried bullseye for amd, it doesn't show 4G either

memtest86+ shows about 3G memory

hp guide says "The memory available may be limited by the operating system."
