[gentoo-user] emerge consistently 'hangs' on kernel/gentoo-sources

[Remco Rijnders]

Hi all,

I've tried googling and didn't get very far so am afraid this might not be a
common thing...

Since a number of months, emerge hangs when doing a upgrade as soon as it gets
to the package gentoo-sources:

>>> Installing (23 of 27) sys-kernel/gentoo-sources-6.1.67::gentoo

It is consistent every time and at the same point. It has been stuck there for
24 hours now. Pressing Ctrl-C takes me back to the command line with no error
indication. Computer load is low, and this is the process tree for emerge:

Anyone has any ideas what might be wrong?

I don't use genkernel so just a guess. It looks like the kernel got 
build and installed but genkernel is stuck 'building out of tree 
module'. Maybe it is trying to fetch some code and not managing to? Try 
checking /var/log/emerge-fetch.log

I tried "genkernel --no-module-rebuild
--kernel-config=/etc/kernels/kernel-config-6.1.19-gentoo-x86_64 all" and this
did result in a succesful compilation. Doing an emerge afterwards finished
emerging the last four remaining packages. Will see if this fixes it going
forward as well!

Thank you all for the suggestions!
