From a5360df9413987ed56ce8cffad678e557eff92e1 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 15 Oct 2010 14:18:21 +0200 Subject: pcmcia/yenta: guide users in case of problems with O2-bridges Some cards need the speedups on, some need them off. As we can't detect this reliably, at least give the users a hint how to tweak the system.
