Linux 6.14 Brings Much Faster Suspend/Resume Times
2025-01-26
Linux kernel 6.14 boasts significantly faster suspend and resume times for some systems thanks to an ACPI update. The change replaces msleep() with usleep_range() in acpi_os_sleep(), reducing spurious delays caused by timer inaccuracies. Testing shows dramatic improvements, with some Dell XPS laptops seeing suspend/resume times drop from 8 seconds to around 1 second. This optimization is particularly beneficial for systems relying on short sleep times, such as those using tight loops with ASL Sleep(5ms).
