Fatal DMA error problem with netbook and BCM4312 - Test 2

2009-12-21 Thread Larry Finger
Hi, I placed a number of test prints in my system trying to find where a DMA data error might occur. In doing so, I found that 3 slots in the DMA header cache cross a page boundary. Such a situation is allowed on my system, but it might be forbidden on Atom processors. Please try this really ugly

[PATCH] b43: N-PHY: clean table init, check PHY rev

It's just compilation-tested as I don't own N-PHY device yet (should receive one for Christmas). Not sure if we even support SSB used for N-PHY cards. From 6800722c2fda0e302d7c759a5f2a993503b6581a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= zaj...@gmail.com Date: Tue, 22
