How odd. I can't see why acpi_ibm would effect IRQs in any way. Are you running with APIC? I am not. Here are the contents of my loader.conf file: #Increase PCM buffer for smoother sound hint.pcm.0.buffersize="16384" kern.maxfiles="25000" # Kick the mouse on resume hint.psm.0.flags="0x2000" # Disable TCC CPU throttling #hint.p4tcc.0.disabled="1" #hint.acpi_throttle.0.disabled="1" # The DVD/CD does DMA just fine hw.ata.atapi.dma="1" # Allow better power management of devices hw.pci.do_power_nodriver="2" hw.psm.synaptics_support="1" # Don't use cpufreq on this system! #cpufreq_load="YES" wlan_scan_sta_load="YES" # VESA allows full res VTYs (132x50 with mode 322) vesa_load="YES" # Support full disk encryption geom_eli_load="YES" # Support IBM ACPI extensions acpi_ibm_load="YES" # Load the sound driver snd_ich_load="YES" acpi_video_load="YES" # Support WEP on WiFi wlan_wep_load="YES" # Don't enable firewall at boot as it breaks IPv6 RDP/NDP #ipfw_load="YES" linux_load="YES" These entries are for a variety of things and some may not be appropriate or may be built into the kernel. I am running the latest available BIOS. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
