Hi Alex, I see that I am currently running 5.4.0-48-generic, which I think is the same version that you originally sent me. But livepatch alters the running kernel without changing its version number, doesn't it? That's what makes me still wonder if it is the culprit. thanks--Jim On Tue, 3 Nov 2020, Jim Cline wrote: > > > > -- Forwarded message -- > Date: Mon, 02 Nov 2020 23:24:48 - > From: Alex Hung <1896...@bugs.launchpad.net> > To: gxgilt...@gmail.com > Subject: [Bug 1896482] Re: acpi event detection crashes > > @jim, > > You can check your kernel version by "uname -r". > > I also built a rebased one: > https://people.canonical.com/~alexhung/LP1896482/Ubuntu-5.4.0-52.57/ -- 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/1896482 Title: acpi event detection crashes Status in linux package in Ubuntu: Fix Released Status in linux source package in Focal: Fix Committed Bug description: = SRU Justification = [Impact] The bug causes the EC driver to fail and ACPI events are no longer handled by Linux kernel, i.e lid close no longer triggers suspends.
