Comment (by rchokshi):
Chris Ball asked us to try out the following:
{{{
Here is a kernel that sets the CERR retry field on the host controller to
zero (infinite retries):
http://dev.laptop.org/~cjb/ronak/
The files need to be copied to:
vmlinuz -> /boot
libertas,usb8xxx.ko ->
/lib/modules/2.6.22*/kernel/drivers/net/wireless/libertas
.. on top of a build542 image
}}}
And this is the result on a B4 XO:
