Have you tried disabling MSI and MSI-X in FreeBSD to see if it makes a difference? Set hw.pci.enable_msi="0" and hw.pci.enable_msix="0" in /boot/loader.conf and reboot. -- | Jeremy Chadwick jdc at parodius.com | ---------------------------- Nope, :( Interrupt usage is still around the 89-95% :( NB sysctl -a | grep msi returns nothing, and attempting to set the values directly returns 'unknown OID' this is on 6.2 GENERIC -------- Still looking for any other hints as to what may be causing this storm. We have tried the msi hints above, with no joy. shutting down USB stuff in the BIOS (no joy), disabling ACPI on boot (this generates a kernel fault and reboots) and different keyboards ( USB only, this thing has no PS/2 ports ) This only thing that made a difference, and that was not totally repeatable was unplugging and re-plugging a keyboard after boot.... then the storm stopped, but we were still without bge1 (a single NIC firewall is kinda useless!)
