Package: firmware-b43-installer
Version: 1:015-14
Severity: serious
I've just done a fresh install of wheezy beta 4 amd64 onto a HP Pavilion
dv2000 laptop
wifi requires firmware-b43-installer
After installing firmware and rebooting, it all works fine, as long as
AC power is connected
If the computer boots without AC power, or if the AC power cable is
removed while the computer is running, the wifi stops working. Wired
ethernet works with or without AC power.
Booting without AC power, I still notice messages about b43 in the dmesg
output
[ 6.448311] b43-phy0: Broadcom 4311 WLAN found (core revision 13)
[ 6.560223] Registered led device: b43-phy0::tx
[ 6.560259] Registered led device: b43-phy0::rx
[ 6.560291] Registered led device: b43-phy0::radio
[ 6.560318] Broadcom 43xx driver loaded [ Features: PMNLS ]
and the module appears to be loaded. However, without AC power, the
wifi controller is completely missing from the output of lspci and no
other wifi commands work (e.g. iwlist). With AC power, I can see this
in lspci:
07:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN

Kernel driver in use: b43-pci-bridge
but without AC power, the lspci output doesn't mention any Broadcom
controller.
It is a dual boot system. In Windows 7 Ultimate, the wifi works fine
with or without AC power.
