            Bug ID: 63865
          Assignee: dri-devel@lists.freedesktop.org
           Summary: radeon_atombios_get_power_modes oops with E-350
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: fdo@zahe.me
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

With linux 3.8.8 on an AMD E-350 cpu, the screen corrupts and freezes during
modesetting switching. The system is otherwise responsive.

Please attach a copy of your vbios.

(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom

Any chance you could bisect?

Possible fix

The attached patch should fix it, but I don't see how any kernel ever would
have worked with your card.  Did you change any bios settings or flash your
bios recently?

I have only changed SATA mode, and have not updated the BIOS since I bought
this motherboard.

3.7.10 works, 3.8.0 doesn't. I'll try to set up bisecting, but this CPU is
really weak.

As another data point, the main OSes boot in UEFI mode. ArchLinux installation
media with 3.8.4 kernel can only boot in BIOS mode, and it works fine.

With the patch, my monitor goes in to stand by right after modesetting (the
power LED is ember instead of blue). dmesg attached.

It looks like you are using a bogus unposted vbios image.  I think you'll need
to bisect.  If I had to guess, I'd say it's related to some change in how the
pci rom images are fetched.

The issue can be reliably reproduced on my E-450. I bisected it to:

----------
commit f9a37be0f02a943d63e3346b19f9c9d8d91826cb

    x86: Use PCI setup data

    EFI can provide PCI ROMs out of band via boot services, which may not be
    available after boot. Add support for using the data handed off to us by
    the boot stub or bootloader.
----------

Looks like your guess is correct.

Additional notes:
- this machine boots in EFI mode as well (via CONFIG_EFI_STUB)
- attached my video BIOS for reference

The version grabbed from boot services hasn't been patches by the sbios yet so
it's not usable by the driver.  Macs need the boot services copy since they
don't provide a way to access it after the OS loads.  On non-Macs we have a
method to fetch the proper vbios via acpi so we don't need this.
