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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884997 Title: no touchpad detected, not working at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1884997/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
