Right now, I have Linus's tree, yours (cited above) and I am, up to now, I had been compiling everything from Linus's v3.2 tag: both a vanilla kernel, as asked by Bjorn and with the patch that I mentioned to Linus ("the one that makes things boot"). If it applies (and newer kernels don't have things which your patch needs), I will keep working with Linus's v3.2 tag. When I compiled from your branch for-pci2 from linux-yinghai.git (without any extra patches), it *did* boot, but noticed one thing weird: using htop and in single user mode, it reported 100% of CPU in use. With regular top, a more fine grained output revealed that no processes were using the CPU, but that almost all of the time was spent in kernel mode. Anyway, as you asked, I put the log of what I see at http://www.ime.usp.br/~rbrito/linux/clevo/2012-01-13-0951-yanghai-for-pci2-branch/ > >> BTW, did you try boot with "pci=use_crs" and not with "acpi=off" ? > > > > I tried, but I got a hang (both with Linux---many versions---and with > > FreeBSD).

Thanks for your (everybody else's) kindness/helpfulness with these multiple issues.
