Hi, I have 2 SuperMicro servers with 11-CURRENT amd64 (r268447 and r292688). Both have LA near 1.0 even without any load. On 'fresh' CURRENT (r292688) top -SH command shows following with debug.acpi.max_threads=8 https://gyazo.com/5e16ffcf803a24171803209dba08848c with debug.acpi.max_threads=1 I have just one process kernel{acpi_task_0} consumed 90%+ WCPU systat -vmstat 1: https://gyazo.com/b8be5305859b7245f6da16f92a1b2165 What is the reason for this behavior, and what can I do with this ? -- wbr, tiger
