Hi,
I recently bought a Compaq 6715s laptop with a Broadcom 4312 wifi chip.
Unfortunately it doesn't work with my Ubuntu Gutsy Gibbon.
When the module is loaded it constantly produces the error
bcm43xx_irq_xmit_error. The ksoftirqd uses 100 % of my CPU time. When I
remove the module from the kernel the computer freezes. Before that it
produced the following output:
Call Trace:

Unfortunately I cannot provide a patch but maybe this will help you
further improving the driver.
