           Summary: Radeon PCI ROM unavailable on Alpha
           Product: Platform Specific/Hardware
           Version: 2.5
     KernelVersion: 2.6.24
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Alpha
        AssignedTo: rth at twiddle.net
        ReportedBy: mattst88 at gmail.com


Distribution: Gentoo
Hardware Environment: Alphaserver DS20L, Radeon X1550 PCI

Problem Description:

Access to the VGA BIOS ROM on my Alphaserver DS20L with a Radeon X1550
PCI does not work. The ROM located at /sys/bus/pci/devices/<pciid>/rom
is blank.

Before starting X, I issue the following commands from the said directory.

echo 1 > enable
echo 1 > rom

rom is empty at this point, which causes X to fail to load when
started. See FreeDesktop bug 15699 for X logs using radeon and
radeonhd drivers.

Only after 'priming' the rom file will X (with radeonhd) load correctly. To
prime it, I issue 'cat rom > /dev/null'.
