Just some suggestions that might (or might not) help. Play with hw.acpi.reset_video and hw.syscons.sc_no_suspend_vtswitch. You may find that you need the jhb acpi_video_dpms patch. I have the following /boot/loader.conf on my T30: cpufreq_load="YES" vesa_load="YES" snd_ich_load="YES" acpi_video_load="YES" acpi_ibm_load="YES" (This is NOT required for resume, but it is nice for a few things. It is the recently posted test version and I don't think it's been committed.) I have the following in my /etc/sysctl.conf on my T30: hw.acpi.reset_video=0 hw.syscons.sc_no_suspend_vtswitch=1 hw.acpi.lid_switch_state=NONE hw.pci.do_powerstate=1 I do notice that I need to switch from my X display to a vty and back after a resume to get the display back. (CTRL-ALT-F1, ALT-F9) The SpeedStep errors are troubling. I have not seen any other reports of this. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
