Screen goes black during bootup ('Waiting for udev uevents to be ...')

I got bitten by the infamous Waiting for udev uevents problem that (according to the intertubes) occured in 2010: *Sometimes* during bootup, right after the kernel prints 'Waiting for udev uevents to be processed' the screen goes black and never recovers. The computer is running fine (I can Ctrl-Alt-F1 to a TTY and reboot), but there's no screen output at all. Backlight stays on. I couldn't make out any pattern as to when it works fine and when the screen dies.
The entire problem seems to have started recently with an update, so it might be the same problem as covered in https://bbs.archlinux.org/viewtopic.php?id=147929. The kernel versions I recently updated are 3.4.7-1 -> 3.4.9-1 and 3.4.9-1 -> 3.5.3-1

This is on an Asus EEEPC (1015BX) with an AMD APU. Under X the GPU is being driven by radeon, but - as written above - the problem occurs way before X even starts. Disabling KMS seems (per my limited statistics) to solve the problem, but leads to other problems. Is there anything I can do to further debug this problem?

Kind regards,
Rufus

I added the kernel parameter

radeon.modeset=0

as described in https://wiki.archlinux.org/index.php/Ke … the_kernel

E.g.:

/etc/default/grub wrote:

GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.modeset=0"

Currently I'm back to 3.4.9 with no problems yet (KMS active), but still keeping my fingers crossed.

I have got this problem the last 2 months. I am back on kernel 3.4.9-1. I have used option "radeon.modeset=1" in menu.lst for last 3 years and it was working without troubles. Has somebody found solution in this issue?

Yes, I do. The option "radeon.modeset=1" does it. I can use  "radeon.modeset=0" and get start of PC, but often system will freeze and I have to restart it.

Adding

video=LVDS-1:d

as kernel parameter worked for me.
