MSIX failure

[Gareth de Vaux]

Hi all, I moved from 8.0-RELEASE to last week's -STABLE:

$ uname -v
FreeBSD 8.1-STABLE #0: Thu Sep  2 16:38:02 SAST 2010 root at XXXXX:/usr/obj/usr/src/sys/GENERIC

and all seems well except my network card is unusable. On boot up:

em0: <Intel(R) PRO/1000 Network Connection 7.0.5> port 0x3040-0x305f mem 0xe3200000-0xe321ffff,0xe3220000-0xe3220fff irq 10 at device 25.0 on pci0
em0: Setup MSIX failure
em0: [FILTER]
em0: Ethernet address: 00:27:0e:1e:5e:e3

em1: <Intel(R) PRO/1000 Legacy Network Connection 1.0.1> port 0x1000-0x103f mem 0xe3120000-0xe313ffff,0xe3100000-0xe311ffff irq 9 at device 1.0 on pci5
em1: [FILTER]
em1: Ethernet address: 00:1b:21:5b:f2:18


em0 is a PCI 'Intel(R) PRO/1000 GT Desktop Adapter' which worked up until now.
em1 is onboard which didn't work with 8.0-RELEASE either.


$ ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
	ether 00:27:0e:1e:5e:e3
	inet XXXXXXXX
	media: Ethernet autoselect
	status: no carrier


pciconf -lv:

em0 at pci0:0:25:0:	class=0x020000 card=0x00008086 chip=0x10f08086 rev=0x05 hdr=0x00
    vendor     = 'Intel Corporation'
    class      = network
    subclass   = ethernet

em1 at pci0:5:1:0:	class=0x020000 card=0x13768086 chip=0x107c8086 rev=0x05 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Gigabit Ethernet Controller (Copper) rev 5 (82541PI)'
    class      = network

(no device listing for em0)

Swapping the PCI card with a PCI-X version gives the same behaviour. Setting
hw.pci.enable_msix and hw.pci.enable_msi to 0 doesn't help in either case.
