General Questions • NAS hangs every now and then when booting

Hello everybody,

I'm new to Debian, but not new to computers. I'm also to some extent familiar with Linux and I'm familiar with the command line / shell.

I have an old Qnap NAS "TS-259 pro+" which is out of support now nice several years. Therefore I decided to give it a try and install Debian on it. The NAS is still x32-bit, so I installed the 32-bit edition of Debian.
I took the DVD image from here https://cdimage.debian.org/debian-cd/cu ... 6/iso-dvd/ and copied it with Rufus to an USB stick. Installation went fine. No obvious problems.

As boot device I use an USB stick with 8GB, because I want to be able to revert to the original firmware, in case things do not work out as expected. (stick is USB 3, while USB port of NAS is USB 2 - just in case this does matter).


The Debian installation on my NAS basically works fine and is working as expected.

BUT every now and then (about 4-6 times out of 10) I have problems booting the NAS. It either boots fine or it hangs after "initial ramdisk ...".

After loading the ramdisk the screen goes black with just a blinking cursor in the upper left corner.
I know that this is expected behavior (for several seconds) - but it's also expected to show the login screen after maybe half a minute.

And here the NAS get's stuck.

I tried removing the "quiet" parameter from GRUB, but that didn't help.
When it boots, I get all the expected messages. If it doesn't boot, I don't get any of those messages. Not a single line...

I changed the kernel params in Grub to look like this:

Code:

"debug earlycon ignore-loglevel keep-bootcon"
hoping to get more information.

This has not led to any significant change.
I get no log output when the boot process hangs.
(Of corse I get plenty of output when the boot process is successful)
So no additional information where it might get stuck.


Oh and just to anticipate some obvious questions:

I have checked the HW of the USB stick (at least 2x). It is fine.
I used a different stick (just in case) --> same behavior.
I tried different USB ports of the NAS --> same behavior.

Some more information, that I thought might help you:

> uname -a
Linux debian-nas 6.1.0-18-686-pae #1 SMP PREEMPT_DYNAMIC Debian 6.1.76-1 (2024-02-01) i686 GNU/Linux


Any ideas?


Many thanks, quack
