Machine worked normally under the RELENG_6. Now, on the RELENG_7 (and CURRENT), attempt to ifconfig ath0 up usualy hangs the machine in the next 2-5 minutes. Hang is hard, I even cannot switch the console to look at the kernel messages or enter the ddb. Also, laptop does not have a serial port or firewire. Not setting the ath0 up, or, unloading snd_hda.ko before activating the interface, allows machine to work. Wireless works without problem, interrupt rate is as expected. hostb0@pci0:0:0:0: class=0x060000 card=0x00901025 chip=0x27a08086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '955XM/945GM/PM/GMS/940GML Express Processor to DRAM Controller' class = bridge subclass = HOST-PCI pcm0@pci0:0:27:0: class=0x040300 card=0x00901025 chip=0x27d88086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82801G (ICH7 Family) High Definition Audio' class = multimedia ath0@pci0:6:2:0: class=0x020000 card=0x04181468 chip=0x001a168c rev=0x01 hdr=0x00 vendor = 'Atheros Communications Inc.' device = 'Atheros AR5005G Atheros AR5005G 802.11abg NIC Chipset / TP-Link (TL-WN551G)' class = network subclass = ethernet wlan: <802.11 Link Layer> wlan: <802.11 MAC ACL support> wlan: mac acl policy registered wlan_amrr: <AMRR Transmit Rate Control Algorithm> ath_hal: 0.9.20.3 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413) ath_rate: version 1.2 <SampleRate bit-rate selection algorithm> pci0: driver added found-> vendor=0x8086, dev=0x27da, revid=0x02 domain=0, bus=0, slot=31, func=3 class=0c-05-00, hdrtype=0x00, mfdev=0 cmdreg=0x0101, statreg=0x0280, cachelnsz=0 (dwords) lattimer=0x00 (0 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns) intpin=b, irq=19 pci0:0:31:3: reprobing on driver added pci2: driver added pci3: driver added pci4: driver added pci5: driver added pci6: driver added found-> vendor=0x168c, dev=0x001a, revid=0x01 domain=0, bus=6, slot=2, func=0 class=02-00-00, hdrtype=0x00, mfdev=0 cmdreg=0x0002, statreg=0x0290, cachelnsz=0 (dwords) lattimer=0x00 (0 ns), mingnt=0x0a (2500 ns), maxlat=0x1c (7000 ns) intpin=a, irq=22 powerspec 2 supports D0 D3 current D0 pci0:6:2:0: reprobing on driver added ath0: <Atheros 5212> mem 0xd0000000-0xd000ffff irq 22 at device 2.0 on pci6 ath0: Reserved 0x10000 bytes for rid 0x10 type 3 at 0xd0000000 ath0: [MPSAFE] ath0: [ITHREAD] ath0: hal channel 2412/a0 -> 1 ath0: hal channel 2412/c0 -> 1 ath0: hal channel 2417/a0 -> 2 ath0: hal channel 2417/c0 -> 2 ath0: hal channel 2422/a0 -> 3 ath0: hal channel 2422/c0 -> 3 ath0: hal channel 2427/a0 -> 4 ath0: hal channel 2427/c0 -> 4 ath0: hal channel 2432/a0 -> 5 ath0: hal channel 2432/c0 -> 5 ath0: hal channel 2437/a0 -> 6 ath0: hal channel 2437/c0 -> 6 ath0: hal channel 2442/a0 -> 7 ath0: hal channel 2442/c0 -> 7 ath0: hal channel 2447/a0 -> 8 ath0: hal channel 2447/c0 -> 8 ath0: hal channel 2452/a0 -> 9 ath0: hal channel 2452/c0 -> 9 ath0: hal channel 2457/a0 -> 10 ath0: hal channel 2457/c0 -> 10 ath0: hal channel 2462/a0 -> 11 ath0: hal channel 2462/c0 -> 11 ath0: hal channel 2467/2a0 -> 12 ath0: hal channel 2467/2c0 -> 12 ath0: hal channel 2472/2a0 -> 13 ath0: hal channel 2472/2c0 -> 13 ath0: using obsoleted if_watchdog interface ath0: bpf attached ath0: Ethernet address: 00:19:7d:74:58:c9 ath0: bpf attached ath0: bpf attached ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps ath0: mac 7.8 phy 4.5 radio 5.6 ath0: Use hw queue 1 for WME_AC_BE traffic ath0: Use hw queue 0 for WME_AC_BK traffic ath0: Use hw queue 2 for WME_AC_VI traffic ath0: Use hw queue 3 for WME_AC_VO traffic ath0: Use hw queue 8 for CAB traffic ath0: Use hw queue 9 for beacons snd_unit_init() u=0x00ff8000 [512] d=0x00007c00 [32] c=0x000003ff [1024] feeder_register: snd_unit=-1 snd_maxautovchans=16 latency=5 feeder_buffersize=16 384 feeder_rate_min=1 feeder_rate_max=2016000 feeder_rate_round=25 pci0: driver added found-> vendor=0x8086, dev=0x27d8, revid=0x02 domain=0, bus=0, slot=27, func=0 class=04-03-00, hdrtype=0x00, mfdev=0 cmdreg=0x0106, statreg=0x0010, cachelnsz=16 (dwords) lattimer=0x00 (0 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns) intpin=a, irq=22 powerspec 2 supports D0 D3 current D0 MSI supports 1 message, 64 bit pci0:0:27:0: reprobing on driver added pcm0: <Intel 82801G High Definition Audio Controller> mem 0xd0240000-0xd0243fff irq 22 at device 27.0 on pci0 pcm0: TCSEL: 0x07 -> 0x00 pcm0: DMA Coherency: Uncacheable / vendor=0x8086 pcm0: Reserved 0x4000 bytes for rid 0x10 type 3 at 0xd0240000 ioapic0: routing intpin 22 (PCI IRQ 22) to vector 57 pcm0: [MPSAFE] pcm0: [ITHREAD] Everything wlan/ath/snd is loaded as modules. alf% uname -a FreeBSD alf 7.0-BETA3 FreeBSD 7.0-BETA3 #46: Tue Nov 27 21:47:09 EET 2007 root@alf:/usr/bsd/obj/usr/bsd/src/sys/ALF i386 Kernel config: #
