To be clear this issue started with Kernel 5.8.0-63 NOT 5.11 (on Focal / 20.04 HWE LTS)
Well Ubuntu Kernel Bot, that's exactly what I did in comment #14 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1937897/comments/14 Latest 5.13 kernel in -prosed on Focal (20.04.3) gets the same gpio errors and warnings in dmesg and "journalctl -b" as with the current 5.11 HWE kernel. X570 Motherboard Ryzen 9 3950X Zen2 CPU Same error appears twice during boot. Here's the output from "journalctl -b" --- sep. 12 15:37:43 tux kernel: gpio gpiochip1: (gpio_aaeon): tried to insert a GPIO chip with zero lines sep. 12 15:37:43 tux kernel: gpiochip_add_data_with_key: GPIOs 0..-1 (gpio_aaeon) failed to register, -22 sep. 12 15:37:43 tux kernel: gpio-aaeon: probe of gpio-aaeon.0 failed with error -22 sep. 12 15:37:44 tux kernel: gpio gpiochip1: (gpio_aaeon): tried to insert a GPIO chip with zero lines sep. 12 15:37:44 tux kernel: gpiochip_add_data_with_key: GPIOs 0..-1 (gpio_aaeon) failed to register, -22 sep. 12 15:37:44 tux kernel: gpio-aaeon: probe of gpio-aaeon.0 failed with error -22 --- They're both "gpiochip1 - GPIOs 0..-1", so why try again right after the first fails? Does NOT appear on my Intel NUC Core i3. It's a 2013 model but runs the exact same kernel at least. Likely not on any Intel based motherboards. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1937897 Title: GPIO error logs in start and dmesg after update of kernel Status in linux package in Ubuntu: In Progress Status in linux source package in Hirsute: Fix Committed Status in linux source package in Impish: In Progress Bug description: [Impact] After upgrade kernel to 5.11.0-25 which introduce some ODM patches from AAEON, user encounters below errors [ 5.852182] gpio gpiochip2: (gpio_aaeon): tried to insert a GPIO chip with zero lines [ 5.852187] gpiochip_add_data_with_key: GPIOs 0..-1 (gpio_aaeon) failed to register, -22 [ 5.852194] gpio-aaeon: probe of gpio-aaeon.0 failed with error -22 [Fix] AAEON provides a patch to check the BFPI version before loading the driver.
