Subject: [ 15/86] b43: Increase number of RX DMA slots
Date: Tue, 26 Feb 2013 16:07:23 -0800	[thread overview]
Message-ID: <20130226235914.483278187@linuxfoundation.org> (raw)
In-Reply-To: <20130226235912.881663118@linuxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit ccae0e50c16a7f7adb029c169147400d1ce9f703 upstream.

Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G
were due to overflow of the RX DMA ring buffer, which was created with 64
slots. That finding reminded me that I was seeing similar crashed on a netbook,
which also has a relatively slow processor. After increasing the number of
slots to 128, runs on the netbook that previously failed now worked; however,
I found that 109 slots had been used in one test. For that reason, the number
of slots is being increased to 256.
