Hi,

Recently I have been encountering an issue that I can't seem to resolve. I'm assuming it as to to with the kernel, but I can't be certain and I am hoping someone can help me out.

I am running Gentoo x64 testing and have emerged to the latest packages (as of today).

During the boot process, the following appears:
Code:

* Mounting /proc ... [ok]
* Mounting /run ...
* /run/openrc: creating directory
* /run/lock: creating directory
* /run/lock: correcting owner
* Caching service dependencies ...


Then the boot process halts at this position (without [ok] from the Caching services dependencies). The boot process will continue if I hit Enter a few times (other keystrokes work too).

A snippet of the dmesg is as follows:
Code:

Between 7.587704 and 163.007621 is where it was hanging. It continued after I pressed Enter a few times.

Hope someone can give me pointers as how I should approach this issue. I am currently at my wits end.

You could increase the verbosity of the kernel log, but that will require a rebuild of your kernel.

Kernel Hacking -> printk and dmesg options -> Default log level [#]
where # is a number, the lower the number the more output.

Interesting you have around 4 network interfaces showing up there. I wonder if it might have something to do with that.

Oh and remove any USB devices (TV sticks or flash drive) if they are attached.
I had a box with a similar delay because they were attached.
