Subject: [PATCH] only try to find radeon IGP ROM on X86
Date: Thu, 10 Oct 2013 14:51:36 +0300 (EEST) [thread overview]
Message-ID: <alpine.SOC.1.00.1310101444090.15296@math.ut.ee> (raw)
In-Reply-To: <CALMQjD8ys=rGGQ5BVfAVPZuN8urr6_xTtCEWq9sYubP4+0bPjQ@mail.gmail.com>
To prevent hangs on non-PC machines (e.g. sparc64), probe Radeon ROM
from ATI IGP only on X86. Fixes hang in this place and allows PCI radeon
detection to move on to next problem.
