Have you tried disabling MSI and MSI-X in FreeBSD to see if it makes a difference? Set hw.pci.enable_msi=3D"0" and hw.pci.enable_msix=3D"0" in /boot/loader.conf and reboot. --=20 | Jeremy Chadwick jdc at parodius.com | ---------------------------- Nope, :( Interrupt usage is still around the 89-95% :(=20 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=20 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!)
