Hi,
The wireless connection keeps failing shortly after being established. Up to now, I've tracked it down to a DMA transmission sequence error in ring 3. Beyond that, I cannot say...
Happy to provide further information and to test any potential fixes.

Firmware was obtained as per b43 wiki page, namely http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2.
In both examples below, I've added a single b43dbg statement to 'b43_dma_handle_txstatus()' which prints out the DMA ring and slot number after the out-of-order sanity check.
I've tried using the driver from Fedora 18 kernel-3.8.2-206.fc18.x86_64 (which is practically the same as the current driver on torvalds/linux.git) and from the latest commit on linville/wireless-testing.git. In both cases, I end up with an 'out of order TX status on DMA ring 3' on slot 138 which leads to an AP disconnect after a while due to inactivity timeout.
In the first case, I get a 'TX-status contains invalid cookie: 0x0000' when slot 138 is the first slot in ring 3. In the second case, it's 'Out of order TX status report on DMA ring 3. Expected 138, but got 126'. After the error, status is given for what would have been the correct slot (i.e. 140, 142, etc...) but obviously slot 138 was not processed so all subsequent status reports get dropped.
The error, at least on my laptop, is easy to reproduce - it happens within a couple of minutes (or less) every time I start using the b43 driver.
The same laptop running Fedora 16 (3.6.11) with the broadcom-wl driver or running Windows 7 works perfectly (at least, no noticeable disconnects). The b43 driver on Fedora 16 (3.6.11) and Fedora 17 (3.7.9) also disconnected but I don't have any debug info to provide for those cases. The broadcom-wl driver on Fedora 18 also works fine until it causes a panic - but before then, no disconnects
I've tried against two different AP with same results.
Using the driver from Fedora 18 kernel-3.8.2-206.fc18.x86_64, the sequence leading up to the failure is:
