If the webcam video is all black, check for a physical switch close to the webcam that allows to turn it on. Pfrenssen (talk) 17:51, 9 October 2024 (UTC)

The section about NFC could use some clarification, as installing neard (or the other recommended packages from NFC) doesn't seem to be enough for it to work. Gianfilippo980 (talk) 12:10, 12 January 2026 (UTC)

Can't reproduce this anymore either unfortunately. What's in /sys/bus/acpi/devices/NXP1001:00/statuson your system? For me it says 0, meaning that ACPI thinks the device isn't present. Lukas (talk) 00:38, 5 February 2026 (UTC)

Hi! For me cat gives out a 15 (with or without a card over the reader), I think that I have also installed the packages that were suggested to me here: https://bbs.archlinux.org/viewtopic.php?id=309772 Gianfilippo980 (talk) 09:51, 5 February 2026 (UTC)

Ok, the issue was twofold:

- When doing a mainboard swap recently, the technician forgot to reconnect the NFC cable to the mainboard, that explained status 0 and nfc0 not appearing

- I went back to the kernel version I was using back then and nfc was working. By manually bisecting arch kernel packages, I found out that nfc broke from 6.17.2 to 6.17.3. The only nfc-related change seems to be https://github.com/torvalds/linux/commit/9c328f54741bd5465ca1dc717c84c04242fac2e1 so I'm now trying to build the nci module with that commit reverted.

I had the NFC reader working when I tried Endeavor OS, but that was back in September/October, so just around that commit. Gianfilippo980 (talk) 18:44, 6 February 2026 (UTC)

I have the same status code 15, I also notice there are tons of interruptions triggered by the nfc device (around 50000 times per seconds base on the output of lsirq ). Unfortunately there are two things I change recently:

(1) I update the whole system software to the newest kernal(6.19.6).

(2) I update my bios from 0.1.45 to 0.1.47 through fwupd and this bios update is irreversible.

Am I the only one meet this irq problem? I even buy a new nfc module pcb and replace it, in case it's the hardware problem, but nothing getting better from it. Teachmain (talk) 13:20, 12 March 2026 (UTC)

Yes, I see a lot of irq 71 (amd_gpio 84 nxp-nci_i2c) btop shows that it constantly uses about 2% of CPU. Gianfilippo980 (talk) 11:48, 26 March 2026 (UTC)
