[SOLVED] Laptop keyboard lag on AMD

CorradoEnea · 2025-09-07 08:04:06

Hi friends. I was installing arch on my laptop with an AMD Ryzen 7 5700U with Radeon Graphics and I had a severe keyboard lag in the ISO installation and also in the system installed. I searched my problem in internet and in this forum, but every possible solutions I found, didn't solve the problem for me. The lag was not present with an external keyboard, but I need to use this laptop without external keyboards.

Is it *only* w/ external keyboards or do those typically come w/ a dock, external monitor and power supply?

If it's really just the keyboard and already affects the console please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

so we can see how that keyboard is wired and whether some quirks already show up.

CorradoEnea · 2025-09-07 16:05:24

No, I have this problem without any external peripherals unfortunately.
This is my system journal

I tried with different kernel parameters and only "noapic" made the keyboard work again but also made the touchpad not working anymore.

The usb device there seems to be https://linux-hardware.org/?id=usb:0bda-0129
Does it help to blacklist that?
Btw, how's the behavior w/ the non-lts kernel?

module_blacklist=rtsx_usb

CorradoEnea · 2025-09-08 09:34:41

Unfortunately, blacklisting rtsx_usb does nothing. I already tried with linux, linux_lts and linux_zen but I had the same problem with every one of them.

seth · 2025-09-08 14:40:35

"atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly." remains after blacklisting rtsx_usb?

If "i8042.dumbkdb=1" or "i8042.direct=1" or "i8042.nopnp=1" don't do anything, try "i8042.debug=1", maybe it provides further hints.

CorradoEnea · 2025-09-08 17:15:14

Unortunately "atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly." remains even after blacklisting rtsx_usb. I tried with i8042.debug=1 and the journal is this.
https://0x0.st/KqYF.txt
I can still see the "atkbd serio0: Failed to enable keyboard on isa0060/serio0", the only difference is that now I have connected an external keyboard because it was a pain logging into my machine without and there are no problem with it.

seth · 2025-09-08 19:40:36

Did you try any of "i8042.dumbkdb=1" or "i8042.direct=1" or "i8042.nopnp=1" ?

In doubt just throw "atkbd.reset=1 i8042.reset=1 i8042.kbdreset=1" at it.

"fa <- i8042 (interrupt, 0, 1)" is the "ACK", not sure how "spurious" that is since there's "f4 -> i8042 (kbd-data)" and "ed -> i8042 (kbd-data)" - but the attempted re/activation in between might mess things up.

CorradoEnea · 2025-09-09 09:29:48

I tried with the non lts kernel with atkbd.reset=1 i8042.reset=1 i8042.kbdreset=1and it gave me this

Have you ever tried "i8042.dumbkdb=1" or "i8042.direct=1" ?

CorradoEnea · 2025-09-09 13:48:14

I tried with i8042.dumbkdb=1 i8042.direct=1
https://0x0.st/Kqdk.txt
which disabled completely the keyboard, then I tried with i8042.dumbkbd=1 i8042.direct=1 i8042.nopnp=1
https://0x0.st/Kqd5.txt
which made the keyboard work again but with the same input lag and then I tried with i8042.dumbkdb=1 i8042.direct=1 i8042.nopnp=1 i8042.reset=1 i8042.kbdreset=1
https://0x0.st/Kqnz.txt
which again made the keyboard not working completely. I don't know if it helps, I'm using hyprland and when I type with the keyboard with the input lag, with a single press of the key, it captures multiple press, like if I'm holding it down

Sep 09 15:33:00 CorradsLaptop kernel: i8042: unknown parameter 'dumbkdb' ignored

Try only "i8042.dumbkbd=1" (DUMB KeyBoarD)

when I type with the keyboard with the input lag, with a single press of the key, it captures multiple press

For clarification: this also happens on the console / multi-user.target, right?

CorradoEnea · 2025-09-09 16:01:17

I have this with only dumbkbd
https://0x0.st/Kq54.txt

No, in the TTY i only have a severe input lag (around 2 seconds to have the input registered, only in hyprland if I type, I have both the lag and the multiple press,

seth · 2025-09-09 16:11:55

You probably don't have autorepeat on the console, the main point is that you've the symptoms there as well.

atkbd and related warnings are gone - do you still get the lag w/ dumbkbd?
And since you've attached an external keyboard: does *using* the internal keyboard produce any errors in the journal now?

Also

I checked with journalctl -f and journalctl -kf and there are no logs while I type with the internal keyboard.

Thank you, I will do it!

Also, I don't know if this can help, but while in hyprland I use the internal keyboard, when the key is being spammed, the touchpad stops working

Means the error messages we got were unfortunately red herrings

Have you tested some live distro like grml.org (or even windows) to make sure this isn't some HW failure?
Resp. does the keyboard behave in the UEFI? Or at the bootloader?

when the key is being spammed, the touchpad stops working

Possibly just because the bus is jammed.

CorradoEnea · 2025-09-09 18:29:09

Yes, the computer came with windows and I had zero problems. Also in GRUB and in the UEFI the keyboard works flawlessly, it doesn't work in the installation neither in the ISO usb.

seth · 2025-09-09 19:52:45

Snooping around a bit, you might run into https://bbs.archlinux.org/viewtopic.php … 1#p2096991 - the objected patch is actually still in acpi/resource.c - but you'd have to build a kernel yourself to test this.

CorradoEnea · 2025-09-10 16:37:59

Ok, I built the custom kernel following that guide, I had to modify the patch but now it is working properly. I'll post the patch here for anyone else facing this issue. Why is this issue still not resolved after all these years? It gives newcomers to Arch a terrible experience.

Idk why the bug was never resolved but you'd have to take that question upstream, either https://bugzilla.kernel.org/show_bug.cgi?id=216118 or https://bugzilla.kernel.org/show_bug.cgi?id=217406
My guess is that it's a limited problem (ACPI will be heavily BIOS/UEFI related) and even if archlinux wasn't super restrictive on applying downstream patches (have yo tried whether the problem exists on other distros?): the applied workaround is certainly no general fix (it'll be necessary to identify why this doesn't work on some system to exclude them) so this has to be sorted out by the kernel/acpi developers anyway.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

I want to thank you, you helped me a lot!

I tried Endeavour OS and the problem was still present, I didn't check with other non arch distros, so I don't know.
