With kernels 3.1 and 3.2, disabling Bluetooth via rfkill also disables my wireless card on my HP Pavilion dm4. This didn't happen with 2.6.41 (I upgraded from Fedora 15 to 16). My devices are set up as this (see attached output of lspci -vnn for details about devices): # rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no 3: hp-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 11: hci0: Bluetooth Soft blocked: no Hard blocked: no The problem is, these commands also stop the WiFi: rfkill block bluetooth and rfkill block 3 [for hp-bluetooth] But this one only kills the Bluetooth: rfkill block 11 Running rfkill block wifi does kill the WiFi, but leaves the Bluetooth up. So it looks like the hp-bluetooth device is the culprit. Sadly, it's what bluetoothd uses by default (if I judge by what gnome-bluetooth does). (If it matters, running 'rfkill block bluetooth' makes hci0 disappear, and after unblocking bluetooth, it reappears with the ID increased by 1. This doesn't happen with the WiFi.) Please ask if I can provide more information/testing. Thanks for your help. --=-+6ER9tLQNNec38WP+T5T Content-Disposition: attachment; filename="lspci.log" Content-Type: text/x-log; name="lspci.log"; charset="UTF-8" Content-Transfer-Encoding: 7bit 00:00.0 Host bridge [0600]: Intel Corporation Core Processor DRAM Controller [8086:0044] (rev 02) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, fast devsel, latency 0 Capabilities: Kernel driver in use: agpgart-intel 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, fast devsel, latency 0, IRQ 41 Memory at b0000000 (64-bit, non-prefetchable) [size=4M] Memory at a0000000 (64-bit, prefetchable) [size=256M] I/O ports at 3050 [size=8] Expansion ROM at [disabled] Capabilities: Kernel driver in use: i915 Kernel modules: i915 00:16.0 Communication controller [0780]: Intel Corporation 5 Series/3400 Series Chipset HECI Controller [8086:3b64] (rev 06) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, fast devsel, latency 0, IRQ 5 Memory at b4406100 (64-bit, non-prefetchable) [size=16] Capabilities: 00:1a.0 USB Controller [0c03]: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller [8086:3b3c] (rev 05) (prog-if 20 [EHCI]) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, medium devsel, latency 0, IRQ 16 Memory at b4405c00 (32-bit, non-prefetchable) [size=1K] Capabilities: Kernel driver in use: ehci_hcd 00:1b.0 Audio device [0403]: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio [8086:3b56] (rev 05) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, fast devsel, latency 0, IRQ 43 Memory at b4400000 (64-bit, non-prefetchable) [size=16K] Capabilities: Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel 00:1c.0 PCI bridge [0604]: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 [8086:3b42] (rev 05) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=01, sec-latency=0 I/O behind bridge: 00002000-00002fff Memory behind bridge: b3400000-b43fffff Prefetchable memory behind bridge: 00000000b0400000-00000000b13fffff Capabilities: Kernel driver in use: pcieport Kernel modules: shpchp 00:1c.1 PCI bridge [0604]: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 2 [8086:3b44] (rev 05) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=02, subordinate=02, sec-latency=0 I/O behind bridge: 00001000-00001fff Memory behind bridge: b2400000-b33fffff Prefetchable memory behind bridge: 00000000b1400000-00000000b23fffff Capabilities: Kernel driver in use: pcieport Kernel modules: shpchp 00:1d.0 USB Controller [0c03]: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller [8086:3b34] (rev 05) (prog-if 20 [EHCI]) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, medium devsel, latency 0, IRQ 20 Memory at b4405800 (32-bit, non-prefetchable) [size=1K] Capabilities: Kernel driver in use: ehci_hcd 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 Mobile PCI Bridge [8086:2448] (rev a5) (prog-if 01 [Subtractive decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=03, subordinate=03, sec-latency=32 Capabilities: 00:1f.0 ISA bridge [0601]: Intel Corporation Mobile 5 Series Chipset LPC Interface Controller [8086:3b09] (rev 05) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, medium devsel, latency 0 Capabilities: Kernel modules: iTCO_wdt 00:1f.2 SATA controller [0106]: Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller [8086:3b29] (rev 05) (prog-if 01 [AHCI 1.0]) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 40 I/O ports at 3048 [size=8] I/O ports at 305c [size=4] I/O ports at 3040 [size=8] I/O ports at 3058 [size=4] I/O ports at 3020 [size=32] Memory at b4405000 (32-bit, non-prefetchable) [size=2K] Capabilities: Kernel driver in use: ahci 00:1f.3 SMBus [0c05]: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller [8086:3b30] (rev 05) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: medium devsel, IRQ 19 Memory at b4406000 (64-bit, non-prefetchable) [size=256] I/O ports at 3000 [size=32] Kernel driver in use: i801_smbus Kernel modules: i2c-i801 00:1f.6 Signal processing controller [1180]: Intel Corporation 5 Series/3400 Series Chipset Thermal Subsystem [8086:3b32] (rev 05) Subsystem: Hewlett-Packard Company Device [103c:146a] Flags: bus master, fast devsel, latency 0, IRQ 21 Memory at b4404000 (64-bit, non-prefetchable) [size=4K] Capabilities: Kernel driver in use: intel ips Kernel modules: intel_ips 01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
