Throughput very low on HP Probook 450 G10

[cyberm8]

Hello,

I've tried shredding disks on computers of a more recent model than usual, and although it works it takes a long time (several hundred hours). Throughput is very low.

Also, ShredOS takes a long time to arrive on the home screen (about 15 minutes), the message "Disabling IRQ #16" is displayed during this time.

I tried it with the latest version of ShredOS (very good features btw), no change.

The PCs that are slow are HP Probook 450 G10s, I have no problems on G7, G8 and G9.

I have swapped disks between a G9 and G10 to rule out disk problems. It seems to be specific to the G10.
I've tried updating the BIOS, with no improvement. I should point out that I have several G10s, so this isn't an isolated case, and the PCs also work very well.

I can manage by shredding from an older PC honestly, but maybe other people with recent hardware will have similar issues?

Thank you

Can you boot ShredOS and post the output of lspci -nn -k on both the G10 and G9 to see what drivers are loading. Thanks.

It has the symptom of a bad SSD, but you said you moved a good Samsung drive to the G10 and that was very slow also?

I came across this comment on Reddit about extremely high failure rates on Hynix drives. What does smartmontools say about the condition of the Hynix drive?

The tests have been performed on two G10. Both were slow.
Computers work well as I reinstalled Debian afterwards, without issue. They have been already used for several months without complaint.

I put a G10 disk into a G9 => boot is fast and shred speed is normal.
I put a G9 disk into a G10 => boot is slow and shred speed is slow.

Below, you can find LSPCI outputs (g9 and g10), dmesg output (g10) and smartctl -a /dev/nvme0n1 output (g10).

When you installed Debian, what was the kernel version? uname -a. I'm just wondering whether to bump to the latest buildroot 24.05 which will give me a updated kernel and drivers.

[cyberm8]

Debian 12 is using kernel 6.1.99-1.

[cyberm8]

I was just wondering. You're implying that you need to update buildroot to get a newer kernel.

I don't know anything about buildroot, but I do know a little about Yocto.
With Yocto, you can specify the kernel version you want.

It seems possible to choose the version.
I'll try to test this on my own: build ShredOS with a 6.1.y kernel.

Compiling an image with an old kernel is not conclusive, I get a black screen once the image is loaded.
The compilation ends without error, strange. I'll keep on digging...

Also, I've tried the previous version of ShredOS ( v2023.08.2_25.0_x86-64_0.35), and it's no better (very slow shreding).

Regarding the black screen, is that with and without nomodeset on the kernel command line in grub.cfg?

[cyberm8]

nomodeset is not set indeed, but I don't need it usually, it works without. I'l will give it a try.

Also, how do you generate an ISO ? I would like to run ShredOS on virtual machines.

Getting back to the original problem, I think the kernel is not involved because the previous version of ShredOS (kernel 6.4) has the issue. I will try an older version.

I think another test is to write data (download a large file with wget for instance) to disk from ShredOS, to rule out a nwipe-related problem.

Hello,

I compiled ShredOS with a newer Buildroot version (buildroot-2024.08.2).

I had a lot of problems due to my lack of knowledge of buildroot.

In the end, with kernel 6.6.62, on an HP Probook 450 G10 computer, no problem: ShredOS boots in a few seconds and the wipe no longer lasts 3 weeks / 1 month.

@cyberm8 good to know, I'll do a rebuild and release as soon as I can.
