From 2d757a7ce06abb4afe5b3002d4cdc40e47d7facc Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Thu, 17 Jun 2010 23:14:04 +0000 Subject: IB/qib: Clear 6120 hardware error register The hardware error register needs to be cleared or another interrupt will be generated, thus causing an infinite loop. This is a regression introduced when removing debug output.
