Description Audiodef 2009-10-05 13:45:09 UTC

On a particular laptop on which I'm doing a fresh install of Gentoo, the system hangs at various points after booting. I've done the install twice. The second time, I synced and emerged -uDN world while chrooted. I have a forums thread:

http://forums.gentoo.org/viewtopic-p-5998450.html#5998450

I don't know what's happening but at this point I don't know what else to do but file a bug, as something appears to be seriously wrong. 

At the last attempt, the system hangs at "Mounting /dev...". No keyboard function, so can't ctrl-d, d, or alt-del. No relevant logs appear in /var/log. 

Reproducible: Always

Steps to Reproduce:
1. Install Gentoo
2. Boot!


Actual Results:  
System hangs.

Expected Results:  
System should boot normally.

I just tried copying /etc/mtab from a working system with the same ~arch, no luck. It still hangs at "Mounting dev..."

You could try to disable udev's coldplug functionality.
On a [arch] system you have to change "RC_COLDPLUG" to "no" in file /etc/conf.d/rc
On a [~arch] system you have to change "rc_coldplug" to "no" in file /etc/conf.d/udev

If this fixes your hangs at boot time, chances are high that there is a kernelmodule causing the hang. You should then try to find out which one it is and add it into /etc/modprobe.d/blacklist.conf

After you did this you should be able to boot the system with udev's coldplug being re-enabled.

Thanks, I will try this next time it happens. I've already used a different stage3 tarball that just works for now. I'm glad I posted this issue, though, in case others run into this problem.
