"amd76xrom" amd76xrom_init_one(): Unable to register resource 0xffc00000-0xffffffff - kernel bug?

[Yaroslav Klyukin <slava@klyukin.com>]

The box has over 12G of ram on an opteron architecture and because of that the SCSI driver fails to
load:


SCSI device sda: drive cache: write back
 sda: sda1 sda2 < sda5 >
sd 0:0:0:0: Attached scsi disk sda

If I boot with mem=1024m , it boots.

Ideas would be highly appreciated!
