Bug ID: 206473 Summary: S2Ram fails resume on x570 (Gigabyte Aorus Ultra) Product: ACPI Version: 2.5 Kernel Version: 5.5.2 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Other Assignee: acpi_ot...@kernel-bugs.osdl.org Reporter: s7...@web.de Regression: No Created attachment 287261 --> https://bugzilla.kernel.org/attachment.cgi?id=287261&action=edit steps and output of steps according to basic-pm-debugging Description: Using a Ryzen 3700x on an Gigabyte Aorus Ultra X570 board resume fails from suspend to ram. Details: using pm-suspend the system successfully suspends to ram (low power consumption seen on monitoring). Actual Result: When issuing wake up (e.g. from Keyboard) power consumption goes up to regular load but no screen/network/disk activation. Screen stays black. Can't ssh into the machine and a spinning disk attached for testing is not spun up. Additional Information: Suspend to disk works fine including resume. Did some pm_testing as good as i understood basic-pm-debugging instructions (see suspend_testing.txt attached) Furthermore a suspend cycle was done with pm_trace [ 1.200795] PM: Magic number: 0:571:178 [ 1.201315] PM: hash matches drivers/base/power/main.c:1331 [ 1.201874] acpi PNP0C02:0b: hash matches [ 1.202396] acpi device:0e: hash matches [ 1.202918] platform: hash matches I found out that PNP0c02 is for Motherboard resources but my knowledge how to investigate beyond that is limited. Source file at 1331 is the trace call of static int __device_suspend_noirq(struct device *dev, pm_message_t state, bool async) .. Complete: complete_all(&dev->power.completion); TRACE_SUSPEND(error); return error; } I used gentoo-sources (5.4.12, 5.5.1) and plain source from kernel.org (5.5.2) same behavior. Did some testing on a windows (10 1903) installation where i could successfully suspend/resume after installing chipset drivers. Not sure where the root of problem is (e.g. bios quirk or sth. else) any help welcome. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
