Subject: [uml-devel] find_iomem hangs up
Date: Wed, 05 Apr 2006 14:01:51 +0400	[thread overview]
Message-ID: <4433958F.3090200@oktetlabs.ru> (raw)

Hi,

When I've build uml with mmapper driver in, and attempted to pass 
something like iomem=xxx,yyy in command line, guest kernel hang up on 
boot. This is because of error in find_iomem - see patch below.
