[SOLVED] current 19/12/2019, kernel modules did not install.

justwantin · 01-03-2020, 04:27 AM

I installed current 19/12/19 on a bananapro two days ago and finally got around to compiling an rtl8192u module for the system today. Compile went well but when I went to put it where it belonged I found that there were no modules installed. I re-installed them manually and all was good afterwards. However, I did a full install less some package groups. the kernel modules package was where it belonged on my install usb. I really don't know what went wrong but if you can't find your kernel modules in current know that you are not alone.

Thanks, I'll add that to the kernel config.

The package contains the Kernel modules, and works on my systems so I suspect a local problem there:

Code:

root@zippy:~# ls /lib/modules/5.4.5-armv7/kernel/
arch/  block/  crypto/  drivers/  fs/  kernel/  lib/  net/  security/  sound/
root@zippy:~# find /lib/modules/5.4.5-armv7/ -type f| wc -l
3728

Did you build the module from source in /usr/src/linux that is provided by the 'kernel-source' package?

Never wanted to bother you about it and anyway I don't learn anything if I'm not challenged

yes, after selecting it in menuconfig and saving

Code:

# make modules_prepare
# make M=staging/rtl8192u

then put it where it belonged in the modules tree.

my apologies .... working from memory ... buffer overrun .. holidays, etc . wrong driver wrong command.

Code:

# make modules_prepare
# make M=drivers/staging/rtl8712

I have re-installed current, it boots and seems to be working fine. However, please note that second time around it still appears that the kernel modules did not install.

Code:

root@bpro10:/home/rick# ls /lib/modules/5.4.5-armv7/kernel/
root@bpro10:/home/rick# find /lib/modules/5.4.5-armv7/ -type f| wc -l
12

I selected 'terse' messages and did see a line saying that 'kernel-modules-armv7-5.4.5_armv7' were being installed. However nothing is there,

Code:

root@bpro10:/home/rick# ls /lib/modules/5.4.5-armv7/kernel/
root@bpro10:/home/rick# find /lib/modules/5.4.5-armv7/ -type f| wc -l
12

but after manually installing I have the same as you

Code:

root@bpro10:/home/rick# installpkg kernel-modules-armv7-5.4.5_armv7-arm-1.txz 
Verifying package kernel-modules-armv7-5.4.5_armv7-arm-1.txz.

It may be a silly question, and it wouldn't be my first, but where did the modules come from I was using before I installed the modules?

Hi

The modules your system has loaded (visible from 'lsmod') come from the initrd '/boot/uinitrd-armv7', and indeed the system will boot into run level 3 without /lib/modules.
You will see some error messages during boot, but only a few.

I don't know what the issue is here, but check /tmp/installpkg-report.log to see if there's any output from that package.
I reinstall my machines regularly and I've never seen that before.

justwantin · 01-05-2020, 01:26 AM

I figured I was running on initrd modules but I wasn't sure. Nothing in /tmp/installpkg-report.log except

Code:

Install report for /usb-stick/slackwarearm-current/slackware/a/kernel-modules-armv7-5.4.5_armv7-arm-1.txz:

aha ... that's it ... I might reinstall current once or twice a year. Your machines get a lot more practice!

Yesterday I installed Slackware ARM current 4 times on RPi2/3/4 devices. Yeah, it was a quiet day.

Reinstall and before rebooting, drop into a shell and check /mnt/lib/modules to see if the modules were installed properly.

OK finished reinstall and mules did indeed install. I have no idea why the didn't install the previous two install. I used the same source on a usb stick and the same b'pro on all three installs.

Code:

root@slackware:/mnt/lib/modules# cd 5.4.5-armv7/
root@slackware:/mnt/lib/modules/5.4.5-armv7# ls
build@             modules.builtin.bin      modules.order
kernel/            modules.builtin.modinfo  modules.softdep
modules.alias      modules.dep              modules.symbols
modules.alias.bin  modules.dep.bin          modules.symbols.bin
modules.builtin    modules.devname          source@
root@slackware:/mnt/lib/modules/5.4.5-armv7# cd kernel/
root@slackware:/mnt/lib/modules/5.4.5-armv7/kernel# ls
arch/  block/  crypto/  drivers/  fs/  kernel/  lib/  net/  security/  sound/
root@slackware:/mnt/lib/modules/5.4.5-armv7/kernel#

With regards to the incorrect date I reported in another thread, the modification date is correct this time around before and after running make clean. I propose to file this all under Stranger Things for lack of a reasonable explanation.

Code:

root@darkstar:/usr/src/linux# ls -l scripts/kconfig/mconf-cfg.sh*
