Subject: [PATCH] pm80xx: fix Adaptec 71605H hang
Date: Sun, 14 Jul 2013 10:25:01 +0200 [thread overview]
Message-ID: <51E2605D.3000301@xs4all.nl> (raw)
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.
