Multi-gpu Quadro NVS 400 (NV17a x2) fails to initialise xserver.

When both of the separate pci bus addresses are used in seperate
devices/screens,  the xserver instance fails.

Also, making the second gpu post first (i think that's what I've managed
to do
- see log3) fails when it is the sole device in use (tried IsolateDevice bus-id
and SingleCard = true options).

The noint10 option makes the loading of the driver / connection detection get
further.

Dual screen using randr on DVI-A-0 and 1 is working.

hi.

looking at my title now, i suppose someone could argue it's fixed, although
i
would be a little upset! the server doesn't crash when one specifies use of
both gpus in a server layout, it just completely ignores the second screen and
hence i get a dual-screen. any attempts to get the xserver to initiate the
second-gpu have not worked.

originally, back in May 2008, the other DAC device and it's two outputs
DVI-A-0
and DVI-A-1 were recognised, if not usable.

now, when isolateDevice '2nd gpu' is used in a quad setup, the xserver
crashes:

#0  NVGetArchitecture (regs=0x0) at nv_driver.c:375
#1  0xb7b37365 in NVPciProbe (drv=0x81eefb0, entity_num=0, dev=0x81eac60,
match_data=0) at nv_driver.c:435

...when isolating the 2nd gpu for a dual screen only, the X server bails with
"no devices attached" -> queue a quick build of the proprietory
blob just to
ensure the card's 2nd gpu was still alive (it is!! ..the blob is still
useless
though).

i'm around on irc too if anyone fancies a semi-interactive debug session?!

cheers.

Server has issues with multiple cards. There's another bug open for this.

(Something to do with libpciaccess if I recall correctly?)
