Hi, i have an HP Proliant DL160 G5 with two hot-plug SATA disks on hot-plug LSI raid controller. I have tried 6.3,7.0 and 8.0 install CDs. It stops at: acpi_button0: <Power Button> on acpi0 With ACPI disabled: p4tcc0: <CPU Frequency Thermal Control> on cpu0 Any suggestions ? I have many DL140G3 without any problems. Matus Zilla
