DetailsDescription:
The boot process inconsistently hangs at "Waiting for UDEV uevents to be processed...", requiring a hard reboot. It hangs about 75% of the time. Hardware: HP Mini with Intel GMA 3150 Detail: I believed the problem was with KMS, since during the occations where the system did boot up fine the console font changed size just after the place where it normally hung. Resolution: Downgraded kernel from [2.6.33.4-1] to [2.6.31.5-1] per <http://wiki.archlinux.org/index.php/Intel#KMS_.28Kernel_Mode_Setting.29>. (Actually that wiki page says to downgrade to [2.6.31.6-1], but I made a mistake.) Then, without rebooting I did a [pacman -Syu] back to kernel [2.6.33.4-1]. Now I can't reproduce the problem. Steps to reproduce: So far, I cannot reproduce it. Status: I'll investigate the cause if it starts to happen again. I'm submitting this report because this contains everything I did. If the problem starts happening again, some of the information above might be relevant. |

it is likely that the problem is not related to KMS;
- i added the modules "intel_agp" and "i915" to MODULES in mkinitcpio.conf
- KMS now happens very early in the boot process
- the boot process still occationally sticks at "Waiting for UDEV uevents etc..."
@wonder: i'm currently still using 2.6.36, but thank you for your suggestion... i'll try other kernels to see if that has any effect
- I ended up never trying kernel 2.6.34, and the problem continued with kernel 2.6.36 inconsistently.
- The problem was less frequent when I blacklisted the kernel modules "acpi-cpufreq", "cpufreq_powersave", and "b43" in "/etc/rc.conf". Hangs still occurred though.
- Just now I've switched to kernel 2.6.35 and done a couple of reboots with the three modules above enabled in "/etc/rc.conf". So far, I've experienced no hangs at boot.
I'll give you an update if the issue continues.
