Hi, beta v2.85.2454 shows an unknown ACPI table. I'm using an Asus P8Z77-V LK board with BIOS version 1001. Debug output of the ACPI section:
However, "CpuPm" includes additional SSDT tables where the unknown table at address 0xDB7D0018 is defined as "CPU0IST".
Name (SSDT, Package (0x0C)
{
"CPU0IST ",
0xDB7D0018,
0x000009AA,
"APIST ",
0xDD866A98,
0x00000303,
"CPU0CST ",
0xDD865018,
0x0000083B,
"APCST ",
0xDD867C18,

})
