From 9504a923924d663e1953f872f0a828e6454a6cfc Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 26 Jul 2013 18:43:45 +0200 Subject: [PATCH] [SCSI] pm80xx: fix Adaptec 71605H hang The IO command size is 128 bytes for these new controllers as opposed to 64 for the old 8001 controller. The Adaptec out-of-tree driver did this correctly. After comparing the two this turned out to be the crucial difference. So don't hardcode the IO command size, instead use pm8001_ha->iomb_size as that is the correct value for both old and new controllers.
