System hang with 80% probability when booting after WPS-start. The startup.cmd window appears, but does not execute anything. Without startup.cmd the WPS just hangs. In the 20% good cases the system works well. Workaround is /MAXCPU=1. The system is an AMD based MSI 785GE53 with 4 core CPU. Old ACPI-versions (possibly before 3.21) worked well in this respect. Please find enclosed the log-file. It took me a huge effort to generate this (Assembling a nullmodem cable and reactivating an old RS-232 laptop)." defect new minor Release 4.00 ACPI PSD 3.21.07
