Comment 1 for bug 192720

Hi Ralf
I can confirm this behavior, I've the same card and my machine locks up at boot time, this is specially delicate since this hardware is installed inside the laptop, so there's no easy workaround other than open the machine and remove the wireless card or rename/delete/blacklist the kernel modules so won't load up at boot time, anyhow this is only feasible by booting an installed old kernel (<= 2.6.24-3-generic, IIRC) or using a livecd, in my opinion this should be take in consideration as soon as possible due the closeness to the distribution release date.

lspci -vvnn -s 02:02.0
02:02.0 Network controller [0280]: Broadcom Corporation BCM4303 802.11b Wireless LAN Controller [14e4:4301] (rev 02)
        Subsystem: Hewlett-Packard Company Unknown device [103c:12f3]
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 64
        Interrupt: pin A routed to IRQ 18
        Region 0: Memory at d0204000 (32-bit, non-prefetchable) [size=8K]

I think is is enough information to start working on this, if not, just ask.

Thanks
