output from dmesg with buffer set to 1M

X starts just fine under 3.12.x for me, but fails under 3.13.x.  I waited for a
few versions to see if the problem would be found/fixed by others, but we're
now up to 3.13.11 (under Fedora 19) and it still fails.  Booting back into
3.12.11 works fine.

Forgive me if more information (beyond the kernel log and Xorg.0.log) would be
helpful... I'm fairly green at working at this level of the O/S.  Please ask
for whatever you need.  lspci shows the graphics card as "NVIDIA Corporation
G86 [Quadro NVS 290] (rev a1)" and the kernel log repors "Chipset: G72 (NV46)",
"Family : NV40".

Again, please let me know if I can provide more useful diagnostic info.

Oh, and at time index 638.685456 of the kernel log I had started switching to
alt-consoles.  Until that point there were no additional log messages
generated.

Thanks,

Adam Benjamin
