Hello, I can confirm this is a kernel bug which manifests on the Lenovo IdeaPad 3 15IIL05.
Attached is a tarball from the Fedora "Problem Reporting" tool which includes the dmesg and other system data. I realize this isn't a Fedora bug tracker but this is a kernel bug and there doesn't seem to be any other discussion about it. Below is the relevant log telling us no handlers are registered for the hardware: [ 9.187109] irq 9: nobody cared (try booting with the "irqpoll" option) [ 9.187113] CPU: 1 PID: 848 Comm: rngd Not tainted 5.6.6-300.fc32.x86_64 #1 [ 9.187113] Hardware name: LENOVO 81WE/LNVNB161216, BIOS EMCN13WW 03/06/2020 [ 9.187114] Call Trace: [ 9.187116] <IRQ> [ 9.187123] dump_stack+0x64/0x88 [ 9.187126] __report_bad_irq+0x35/0xa7 [ 9.187128] note_interrupt.cold+0xb/0x6a [ 9.187129] handle_irq_event+0x88/0x8a [ 9.187130] handle_fasteoi_irq+0x78/0x1c0 [ 9.187132] do_IRQ+0x50/0xe0 [ 9.187133] common_interrupt+0xf/0xf [ 9.187134] </IRQ> ** Attachment added: "oops-2020-07-28-14.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1884997/+attachment/5396681/+files/oops-2020-07-28-14.tar.gz -- 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/1884997 Title: no touchpad detected, not working at all Status in linux package in Ubuntu: Incomplete Bug description: hello, i bought a new pc and installed ubuntu 20.04 and windows 10 on it. on ubuntu os my touchpad doesn't work at all, since installation process but it does on windows. the pc is a lenovo pc and one of the latest released one. when i plug in a usb mouse the mouse works fine but the touchpad still don't. it even doesn't show the touchpad when i type in (1) "cat /proc/bus/input/devices". only the usb mouse twice. i tryed a lot and don't know how to help myself any further. i attached a file "devices" where printed my output of (1). thanks for any help.
