Hi there, I didn't check the dmesg messages of 6.0 too closely before I've upgraded to 6.0-RC1 and accidentally found two strange lines about $PIR in the following chunk of the dmesg: pcib0: <Host to PCI bridge> pcibus 0 on motherboard pir0: <PCI Interrupt Routing Table: 6 Entries> on motherboard pci0: <PCI bus> on pcib0 $PIR: No matching entry for 0.7.INTD agp0: <VIA 82C597 (Apollo VP3) host to PCI bridge> mem 0xd8000000-0xdbffffff at device 0.0 on pci0 pcib1: <PCI-PCI bridge> at device 1.0 on pci0 pci1: <PCI bus> on pcib1 $PIR: ROUTE_INTERRUPT failed. pci1: <display, VGA> at device 0.0 (no driver attached) isab0: <PCI-ISA bridge> at device 7.0 on pci0 All devices of this system work fine with 6.0 (previous betas and current RC). ACPI is disabled. I can send the full dmesg or full verbose dmesg output, if you need. I'm just interesting, are those two lines showing any potential problem that others may experience on different hardware? For example, in the freebsd-stable@ mailing list archive I've found a Michel Talon's report about running 6.0-RC1 with RealTek 8029 based NIC under qemu: http://docs.freebsd.org/cgi/mid.cgi?20051012094243.GA48295 I have the same NIC made by Genius that works fine on 6.0-RC1, not under qemu: ed0: <RealTek 8029> port 0xec00-0xec1f irq 9 at device 10.0 on pci0 ed0: Ethernet address: 00:c0:df:f3:8a:56 ed0: type NE2000 (16 bit)
