From 414128bd33fef3242747154dfa444970bc5caf4c Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 4 Sep 2009 09:13:49 +0100 Subject: [PATCH] x86: Increase timeout for EHCI debug port reset completion in early printk On one of my systems, several thousand iterations are needed before CMD_RESET can be observed clear after setting it. Using a much higher value here obviously cannot hurt.
