[SOLVED]Boot Delay while loading modules
Im experiencing a quite long delay on the boot process, more exactly, while arch is loading the modules. Im using the MOD_AUTOLOAD option, and i wanted to know if someone knows of a way to track down the delay to a specific module...

Re: [SOLVED]Boot Delay while loading modules
hwdetect --show-modules lists all the modules that hwdetect attempts to load, barring blacklisted ones. After booting up, modprobe -r all your modules, then modprobe them from the list, one by one.

Re: [SOLVED]Boot Delay while loading modules
Boot into single-user mode, disconnect any peripherals, etc. Do lsmod to see what's been loaded, work out why, and go from there.

Re: [SOLVED]Boot Delay while loading modules
Actually found the module causing the slowdown:

Re: [SOLVED]Boot Delay while loading modules
I don't know anything about this hardware but you can add module name to hwdetect blacklist in rc.conf. Reboot, and try to modprobe the module from command line. Check dmesg/logs for any errors produced by the module. Maybe this driver needs some parameters (modinfo says it has a few)?

Re: [SOLVED]Boot Delay while loading modules
Actually, the only output modprobing the module is giving (dmesg) is the following:
ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 16 (level, low) -> IRQ 16
PCI: Setting latency timer of device 0000:00:1b.0 to 64but i really dont know what to do with it apart from googling it ...

Re: [SOLVED]Boot Delay while loading modules
Hmmm, maybe blacklist the module and add "modprobe snd-hda-intel &" in /etc/rc.local so it loads at the very end...

Re: [SOLVED]Boot Delay while loading modules
Thanx for the advice, at least now the delay remains in background and doesnt affect boot up speed 
but would anyway like to know what is causing this...

Well, it'd be caused by the module itself not meshing well with your hardware - it might be best to contact whoever makes that module with the problem... or maybe see if the same thing happens under archie or knoppix or something...
