hey guys , I am having a real slow boot (hanging on the "waiting for udev uevents to be processed") I've tried to see what takes so long (bootchart) and I find that modprobe hangs for about 40 seconds .. how can I see what module takes so long ?
* booting with : nomodeset , acpi=off , noapic
is not working
** I have a nvidia card
*** bootchart : http://i.imgur.com/uIm5H.png
thanks in advance for your time

Not really helpful, I know :-(
Is it a fresh install or was it OK before and it started acting up recently? If the latter, you can downgrade until sb figures out what's wrong or the problems goes away by itself.

thank you for your comment I will check these out.
I have already tried googling and some of the solutions on the forum nothing worked (including disconnecting everything)
but I do believe its something with the package as I use arch for quite long now and this problem suddenly appeared after an update.
anyway I wanted a clean install and I just reinstalled arch the problem continue so I guess its the package
(I ignored it as I boot up the computer once in a week but now I tend to shut it down in the nights so its annoying)

Have you tried downgrading? Maybe you can get away with an older version.

I did.
I have had the udev-162 so I went here : http://repos.archlinux.org/wsvn/packages/udev/trunk/
and downloaded udev 160 (which according to the time log was just about when it happened first) and udev 158 , udev 150
made packages of them all and installed the udev 160 -- rebooting , the problem persists.
installed the udev 158 -- problem still there.
attempt installing udev 150 -- :: udisks: requires udev>=157.
this is where I stopped.
I did not really dig into it but I've seen alot of rules in the udev rules.d folder. what rules are necessary to boot ? so maybe I can isolate some...
or maybe is this even related ?
any other solution that might work?
thanks in advance

I have quite similar problem here.
Except my machine doesn't boot but spits out a bunch of weird errors(picture]).
I've found out that file /lib/udev/rules.d/80-drivers.rules
# do not edit this file, it will be overwritten on update
ACTION=="remove", GOTO="drivers_end"
DRIVER!="?*", ENV{MODALIAS}=="?*", RUN+="/lib/udev/load-modules.sh $env{MODALIAS}"
SUBSYSTEM=="tifm", ENV{TIFM_CARD_TYPE}=="SD", RUN+="/lib/udev/load-modules.sh tifm_sd"
SUBSYSTEM=="tifm", ENV{TIFM_CARD_TYPE}=="MS", RUN+="/lib/udev/load-modules.sh tifm_ms"
SUBSYSTEM=="memstick", RUN+="/lib/udev/load-modules.sh ms_block"
SUBSYSTEM=="memstick", RUN+="/lib/udev/load-modules.sh mspro_block"
SUBSYSTEM=="i2o", RUN+="/lib/udev/load-modules.sh i2o_block"
SUBSYSTEM=="scsi", ENV{DEVTYPE}=="scsi_device", TEST!="[module/sg]", RUN+="/lib/udev/load-modules.sh sg"
SUBSYSTEM=="module", KERNEL=="parport_pc", RUN+="/lib/udev/load-modules.sh ppdev"
LABEL="drivers_end"
causes the problem for me(actually the line with DRIVER!=... because once I comment it out - the boot process doesn't freeze)
By the way. Even though I can boot my computer no keyboard or mouse works in KDE. But TabletPC touchscreen works.
Is there a way i can do some diagnostics?

Can you post it? Maybe you should open another thread (and link to this one if you like).
@ liorc666
Do you have any unusual udev rules you would like to share?

I have edited my previous reply. Is is ok to create another post, basically a duplicate?

I find it quite a difference whether sth boots albeit slowly v. doesn't boot at all.

You see - it has nothing to do with the OP's problem.
I think it will be better if you open another thread and post a link to your /var/log/Xorg.0.log
Yes, you can create another thread, with or without that post. Such branching isn't forbidden.

these are all my rules , but I dont believe its something that added up as when this installation was a clean install I've had the exact problem.
which rules might've caused the problem ? I can play a bit trial and error I guess
Offline
And you didn't modify any of the stock rules?
I see you have RAID, so maybe it's a normal thing with RAID?
Offline
well my disks are not in a RAID also I did not modify anything with the rules
