Details

When booting reaches the "Loading UDev uevents" stage, the screen goes blank. Booting continues and it is possible to login in and run commands "blind". These pointers may help: I tried 0.8b2 ftp install and I had this problem on first boot. I then tried installing with the base ISO and booting was normal. I kept a copy of /etc/udev/ and did a pacman -Syu. The problem appeared on next boot so I replaced the new /etc/udev/ with the copy of the original and next boot was OK. I proceeded to install XFCE4 but on the next boot the problem appeared again, replacing /etc/udev/ with the original did not help. It was still possible to log in and start xfce with some difficulty (from a second console) but everything was extremely slow and rendering of windows (thunar) was incomplete.

My system is Athlon 64X2 on AUSUs A8N mobo and Radeon R300 vga card.
This task depends upon

which udev and kernel version do you use exactly?
blanking screens make me think of collision with partial enabeld framebuffer drivers.

I have udev-106-1 and kernel26-2.6.20.3-2 according to /var/log/pacman/local. The installation is 0.8b2 but same problem occurs with 0.7.2. With both versions, problem occurs after -Syu after installing from base iso. If I do an ftp install, problem is there from the beginning, e.g. seems to be related to some of the latest packages. I cannot compile a custom kernel since the screen is blank :-(

OK, I re-installed 0.8b2 from base ISO and then tried following:

pacman -Sy
pacman -S udev
reboot - all OK, seems udev not to blame.
pacman -S kernel26
reboot - screen goes blank after "Loading UDev uevents"
I kept a copy of original vmlinuz26 and kernel26.img but returning to
these didn't help. Seems its upgrade to kernel26-2.6.20.3-3 to blame?

Final Clue:
Fresh install from 0.8b2 base ISO
Download latest vanilla kernel 2.6.20.3 and custom compile/install
pacman -Syu to update all
reboot - all OK including xfce4 (writing this in arch 0.8 using firefox)

Seems to me that the problem is with the config of arch kernel26-2.6.20.3-2
that makes stock kernel somehow incompatible with my hardware. I guess this
problem may not bug others as few if any would install arch i686 on an AMD64
machine (I need god damned firefox flash etc plugins to browse some sites)
