SRU: https://lists.ubuntu.com/archives/kernel- team/2022-February/128284.html (J/I/oem-5.14)
** Description changed: + [SRU Justification] + + [Impact] + + On some platforms, PS/2 keyboard cannot wake system up from s2idle. + + [Fix] + + Mainline commit cb1f65c1e142 ("PM: s2idle: ACPI: Fix wakeup interrupts + handling") picks up the missed wakeup interrupt. + + [Test Case] + + Use button press on PS/2 keyboard to wake suspended system. + + [Where problems could occur] + + It may still discard irqs under some very rare corner cases that are not + yet identified, but the implementation can be extended easily when + necessary. + + [Other Info] + + This affects 5.4+ kernels and has been proposed for linux-stable. While + this is merged in v5.17-rc4, linux-unstable will have this soon so + nomination is skipped. + + ========== original bug report ========== + With bug 1957026 and bug 1960434, suspend/resume using rtc and power button work as expected, but PS/2 or USB keyboard still do not work well as an wakeup source. This focus on fixes for PS/2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1961739 Title: PS/2 Keyboard wakeup from s2idle not functioning on AMD Yellow Carp platform To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1961739/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
