Package: linux-image-2.6.16-1-k7
Version: 2.6.16-7
Severity: normal

Loading both the amd76x_edac module and the amd_k7_agp module in either 
order stops the second module from being initialised.  This appears to 
be because they're both associated with the same host bridge, class 
0600, device 1022:700e.

In my case, I prefer working AGP to EDAC, so I've created a new file in 
/etc/hotplug/blacklist.d/ to prevent amd76x_edac from being loaded 
automatically.  However, I don't see why both modules shouldn't be able 
to be loaded at the same time.


When amd76x_edac is loaded first, I get these messages from dmesg 
during boot:

MC: drivers/edac/edac_mc.c version edac_mc  Ver: 2.0.0 Apr 15 2006
EDAC MC0: Giving out device to "amd76x_edac" AMD761: PCI 0000:00:00.0

then later, when X starts:

[drm] Initialized radeon 1.22.0 20051229 on minor 0
[drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held
[drm:drm_unlock] *ERROR* Process 3963 using kernel context 0


With amd76x_edac blacklisted, I get:

agpgart: Detected AMD 761 chipset
agpgart: AGP aperture is 64M @ 0xe0000000

then:

[drm] Initialized radeon 1.22.0 20051229 on minor 0
agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode
agpgart: Putting AGP V2 device at 0000:01:05.0 into 1x mode
[drm] Loading R300 Microcode


PCI 0:1:5.0 is my Radeon 9550, class 0300, device 1002:4153.

most likely fixed since no other update on that issue,
thus closing.
