Boot seems to hang on *Calculating Module Dependencies

On booting there is a long pause on the *Calculating Module Dependencies step. Is this normal? Can it be accelerated?

It's normal for there to be a pause. It shouldn't be long, unless you have a slow hard disk and CPU.

hi,

up until today gentoo (2005.0) has been working fine: my HD is new & CPU is pretty good so i never really noticed any long pauses at this step.

Now, though, it permanently (well, 30mins - couldn't be bothered waiting any longer) hangs at the *Calculating Module Dependencies stage.

As i said it was fine up until then, and i cant remember doing anything that would seriously mess up my system.

any ideas?

thanks.

I've been having the same problem on my Dell XPS laptop (3.4 MHz P4)... It was working fine with gentoo-sources-2.6.12-r10, but when I try going to 2.6.13-r3 it's just dog slow... using the 2.6.12-r10 config as a base for genkerneling 2.6.13-r3. it seems to get really slow right around where it says it's using balanced irq, ipi shortcut mode, and freeing unused memory...

i thought i just nailed it after disabling balanced irq's in the kernel but then it sat and thought a while at Coldplugging usb devices... until i pressed SysRq (maybe it woke it up, maybe just coincidence) and the slowness continues.

found it!

I applied the patch in comment #16 to gentoo-sources-2.6.13-rc5, rebuilt the kernel, and problem solved!

problem's associated hyperthreading and choosing the appropriate C-state on boot...
