Hello, Thanks for submitting this bug. Did this happen after an update? What was the last version working for you for both series?
If I am not mistaken we don't have 6.8.0-83 for noble? We have released 6.8.0-84 version recently. Can you update you system and try with the latest version. For jammy we do have 5.15.0-153, but this seems outdated as well. We now have 5.15.0-156, can you update jammy and try again as well? -- 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/2125250 Title: UBSAN: array-index-out-of-bounds in /build/linux-1ylo5V/linux-6.8.0/drivers/input/mouse/focaltech.c:221:17 Status in linux package in Ubuntu: New Bug description: I'm facing this error in the journal.
