2.6.27-rc5 cannot even boot (AMD64, quad-core, AHCI-SATA)

First: thanks for the nice new features all the time (I hope full XEN 
support will be in-kernel soon).

I currently run a 2.6.26.3 kernel which works (on the machine I type 
this e-mail). I tried 2.6.27-rc4, works too. But -rc5 does not even 
boot, and I have no idea how to produce a log of what's happening as it 
doesn't even find the disks.

As far as I could read on screen, there are some "PCI INT A" not 
resettable for AHCI-SATA, and all the USB drivers do NOT load as it 
cannot reset the controller. So even my keyboard does not work, as it's 
USB.

The mainboard is an ABIT AX78, with an AMD Phenom(tm) 9850 Quad-Core 
Processor, 8GB RAM. I attach a bit of hardware info (lspci, lsmod, 
kernel-config files from 2.6.26.3 and .27-rc5), so maybe somebody finds 
it useful.

In case of questions please contact me directly, I am not on this list.

It looks like the issue I was having with -rc5 on my Phenom box and it should
be fixed in the current mainline kernel (-rc5-git5).

Perhaps it's due to the same chipset/BIOS issue.

Thanks,
