Modified Files: src/sys/external/bsd/acpica/dist/executer: exsystem.c Log Message: exsystem.c: revert ACPI warning about sleep values >10ms acpica 20220331 introduced the following change: For the ASL Sleep() operator, issue a warning if the sleep value is greater than 10 Milliseconds. Quick boottime is important, so warn about sleeps greater than 10 ms. Distribution Linux kernels reach initrd in 350 ms, so excessive delays should be called out. 10 ms is chosen randomly, but three of such delays would already make up ten percent of the boottime. This can generate many console messages like: [ 26.055036] ACPI Warning: Firmware issue: Excessive sleep time (0x0000000000000064 ms > 10 ms) in ACPI Control Method (20220331/exsystem-239) (60 of them in the latest boot on one older Ivy Bridge laptop.) This has been reverted upstream and is not present in the next release. https://github.com/acpica/acpica/commit/df896f452f945d498736c5775d4ee6629df31786 (Also previously reverted in FreeBSD and Linux.)
