Confirmed. Just updated and same. Can you backport the fix to the 20.04 HWE kernel? I mean that's the one Canonical recommends has as first choice if downloading Ubuntu from ubuntu.com, for years now. And they've become more stable in my experience than the ones between LTS versions, which is good. The others should be more testing grounds and those who can live with having to fix possibly basic stuff.
And definitely more common nowadays that third party software outside repos (incl. PPAs), proprietary or not, often lists only the latest or two latest LTS versions as supported and downloads (repo or deb package). Tried Ubuntu 21.04 some months ago, just to see if something new cool stuff, in a VM (IIRC, or it was a USB stick) and well let's say KVM+QEMU or my PC, me either, didn't like it. Boot warnings, even red errors from systemd on a clean updated install, and several (official) packages that are in the repos didn't even launch, some DKMS modules failed... Can't use that as a primary workstation + server. With snaps etc you can run pretty bleeding edge both desktop and CLI stuff like certbot (Let's Encrypt) on 20.04, so. Snaps use an 18.04 core - makes sense for compatibility. Doesn't stop you from the latest Blender version or whatever. -- 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: Fix Released Status in linux source package in Hirsute: Fix Committed Status in linux source package in Impish: Fix Released 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.
