From mboxrd@z Thu Jan 1 00:00:00 1970 From: chris at martin.cc Date: Mon, 30 May 2011 23:01:27 +1000 Subject: BCM5354 (Asus WL500GPv2) DMA RX buffer too small and skb_over_panic In-Reply-To: References: <4DE22C0E.1050902@hauke-m.de> <4DE25A8F.6040606@lwfinger.net> Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: b43-dev@lists.infradead.org I have not tested this issue for a while now. I will set up the latest OpenWrt trunk with the old firmware and current b43 driver on a broadcom 5354 and stress test it over the next few days and report back The more recent firmware still crashes with the b43 driver on the broadcom 5354 chip set, I tested it last week. cheers ---------------------------------------------------------- Chris Martin m: +61 419 812 371 ---------------------------------------------------------- 2011/5/30 Rafa?
