Bug#872410: AHCI module not loaded when using preseed

[Jörg Schulz]

Still having this problem with buster and newer hardware "Intel NUC8".

Sometimes the ahci module gets loaded without any modification
of the installer (/bin/hw-detect).

When using the old hack
> d-i preseed/early_command string
>   sed -i '/^update-dev >.dev.null$/i udevadm control --reload'
>   /bin/hw-detect
the ahci module seems to be loaded reliably.

Hello Jörg,

All the lines you suggested me work for my problem. I put the third in my 
configuration.

Hello Gilles,

with this HACK you don't have to modify your kernel, initrd or 
udeb-repository. Simply add this line to your preseed file:

d-i preseed/early_command string sed -i '/depmod -a > .dev.null 2>&1 || 
true/a modprobe ahci || true' /bin/hw-detect

It tries to modify /bin/hw-detect to unconditionally try to load the 
ahci module after the "depmod -a"-command at the beginning of the 
script. hw-detect is called (at least) 2 times before partitioning.
First for network-detect (at this time the sata-modules-udeb is
obviously not available and modprobe will fail) and a second time form 
disk-detect. Now the sata-modules-udeb should have been installed 
already and the ahci-module is ready to install - after "depmop -a" of 
course.

This is no solution for the root cause of the problem.

To further investigate this it would be nice if you could confirm my 
guess of a timing problem. For this you could add this line to your 
preseed file (instead of the above of course):

d-i preseed/early_command string sed -i '/^update-dev >.dev.null$/i 
sleep 10' /bin/hw-detect

or this:

d-i preseed/early_command string sed -i '/^update-dev >.dev.null$/i 
udevadm control --reload' /bin/hw-detect

Hope this helps.

Jörg

Well, I've been busy trying to put pieces together to release D-I Buster
Alpha 1. Now, your mails are amongst 800+ unread ones in my debian-boot@
folder. Maybe others have more free time than I have. In any cases, when
someone has time to look into your issue, you'll get a reply.

Bug#872410: AHCI module not loaded when using preseed

[Gilles MOREL]

Hello,

Is that possible to have any nows about this bug, I still don't have any answer 
since mid-August.
Pearhaps you're working on it, but I don't know because I have no answer to my 
last two messages.

This is my first bug report, so I don't know how it is supposed to work.

This is strange, it seems the sata-modules udeb is fetched just fine,
I'm not sure why ahci wouldn't be loaded.

linux.git has this as its configuration:

debian/installer/modules/sata-modules:drivers/ata/ahci* ?

so ahci* modules should end up in that udeb, and that's indeed the
case for what I can see.

Are you using brand new hardware for which support might be missing?
Is the non-preseed installation loading appropriate modules… on the
same HW as the failing preseed installation?

[Gilles MOREL]

Hello,

I don't know this message is for me, but I don't know what is a 'depmod' and I 
don't know how to add one in the installer, considering I use the netinstaller 
from debian-installer-9-netboot-amd64 package.

Could this be due to a missing 'depmod' in the installer?

Bug#872410: AHCI module not loaded when using preseed

[Gilles MOREL]

Hi Cyril,

The ahci kernel module does exist in debian-installer, I can load manually and, 
then, the hard drive appears, but too late.
When I manually install, the kernel modules are correctly (that is to say 
xhci_pci AND ahci).
The hardware was bought in 2016.

I don't know about linux.git configuration, I don't use it in debian-installer.
