I wasn't there at the time, but a coworker said that after he touched the keyboard it seemed to come back to life. We decided to move to 6.2-PRERELEASE after that incident to see if would help. So far, we haven't had another incident of that type, but it hasn't been running for more than a few days with the changes. I also have not had the chance to test the recent if_em merge. Just to note, I have the usb controller disabled in the bios due to it causing interrupt problems with the em NIC when I first installed 6.1-RELEASE as others have reported. I haven't tried turning it back on to see if the problem remains. The apic is also enabled (SMP box). I have not tried enabling DEVICE_POLLING. data point: em0: flags=8843 mtu 1500 options=b inet xxx.xxx.1.5 netmask 0xffff0000 broadcast xxx.xxx.255.255 inet xxx.xxx.1.91 netmask 0xffffffff broadcast xxx.xxx.1.91 inet xxx.xxx.1.8 netmask 0xffffffff broadcast xxx.xxx.1.8 inet xxx.xxx.1.56 netmask 0xffffffff broadcast xxx.xxx.1.56 ether 00:13:72:4b:70:e7 media: Ethernet autoselect (1000baseTX ) status: active em1: flags=8802 mtu 1500 options=b ether 00:13:72:4b:70:e8 media: Ethernet autoselect status: no carrier lo0: flags=8049 mtu 16384 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 interrupt total rate irq1: atkbd0 1195 0 irq4: sio0 12374 0 irq6: fdc0 12 0 irq14: ata0 140 0 irq46: amr0 32780148 98 irq64: em0 65465147 196 cpu0: timer 663314472 1993 cpu1: timer 663568256 1994 Total 1425141744 4282 hostb0@pci0:0:0: class=0x060000 card=0x016d1028 chip=0x35908086 rev=0x09 hdr=0x00 vendor = 'Intel Corporation' device = 'E752x Server Memory Controller Hub' class = bridge subclass = HOST-PCI pcib1@pci0:2:0: class=0x060400 card=0x00000050 chip=0x35958086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = 'E752x Memory Controller Hub PCI Express Port A0' class = bridge subclass = PCI-PCI pcib4@pci0:4:0: class=0x060400 card=0x00000050 chip=0x35978086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = 'E752x Memory Controller Hub PCI Express Port B0' class = bridge subclass = PCI-PCI pcib5@pci0:5:0: class=0x060400 card=0x00000050 chip=0x35988086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = 'E752x Memory Controller Hub PCI Express Port B1' class = bridge subclass = PCI-PCI pcib8@pci0:6:0: class=0x060400 card=0x00000050 chip=0x35998086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = 'E752x Memory Controller Hub PCI Express Port C0' class = bridge subclass = PCI-PCI pcib11@pci0:30:0: class=0x060400 card=0x00000000 chip=0x244e8086 rev=0xc2 hdr=0x01 vendor = 'Intel Corporation' device = '82801BA/CA/DB/DBL/EB/ER/FB (ICH2/3/4/4/5/5/6), 6300ESB Hub Interface to PCI Bridge' class = bridge subclass = PCI-PCI isab0@pci0:31:0: class=0x060100 card=0x00000000 chip=0x24d08086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82801EB/ER (ICH5/ICH5R) LPC Interface Bridge' class = bridge subclass = PCI-ISA atapci0@pci0:31:1: class=0x01018a card=0x016d1028 chip=0x24db8086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82801EB/ER (ICH5/ICH5R) EIDE Controller' class = mass storage subclass = ATA pcib2@pci1:0:0: class=0x060400 card=0x00000044 chip=0x03308086 rev=0x06 hdr=0x01 vendor = 'Intel Corporation' device = '80332 [Dobson] I/O processor A-segment Bridge' class = bridge subclass = PCI-PCI pcib3@pci1:0:2: class=0x060400 card=0x00000044 chip=0x03328086 rev=0x06 hdr=0x01 vendor = 'Intel Corporation' device = '80332 [Dobson] I/O processor B-segment Bridge' class = bridge subclass = PCI-PCI amr0@pci2:14:0: class=0x010400 card=0x016d1028 chip=0x00131028 rev=0x06 hdr=0x00 vendor = 'Dell Computer Corporation' class = mass storage subclass = RAID pcib6@pci5:0:0: class=0x060400 card=0x00000044 chip=0x03298086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = '6700PXH PCI Express-to-PCI Express Bridge A' class = bridge subclass = PCI-PCI pcib7@pci5:0:2: class=0x060400 card=0x00000044 chip=0x032a8086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = '6700PXH PCI Express-to-PCI Express Bridge B' class = bridge subclass = PCI-PCI em0@pci6:7:0: class=0x020000 card=0x016d1028 chip=0x10768086 rev=0x05 hdr=0x00 vendor = 'Intel Corporation' device = '82547EI Gigabit Ethernet Controller' class = network subclass = ethernet em1@pci7:8:0: class=0x020000 card=0x016d1028 chip=0x10768086 rev=0x05 hdr=0x00 vendor = 'Intel Corporation' device = '82547EI Gigabit Ethernet Controller' class = network subclass = ethernet pcib9@pci8:0:0: class=0x060400 card=0x00000044 chip=0x03298086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = '6700PXH PCI Express-to-PCI Express Bridge A' class = bridge subclass = PCI-PCI pcib10@pci8:0:2: class=0x060400 card=0x00000044 chip=0x032a8086 rev=0x09 hdr=0x01 vendor = 'Intel Corporation' device = '6700PXH PCI Express-to-PCI Express Bridge B' class = bridge subclass = PCI-PCI none0@pci11:13:0: class=0x030000 card=0x016d1028 chip=0x51591002 rev=0x00 hdr=0x00 vendor = 'ATI Technologies Inc' device = 'RV100 Radeon 7000 / Radeon VE' class = display subclass = VGA -- Russell A.
