Summary:	USB keyboard/mouse don't work when kernel is compiled by genkernel 3.0.1_beta4/5
Product:	Gentoo Linux	Reporter:	giovanni.bobbio
Component:	[OLD] Core system	Assignee:	Brad House <brad>
Status:	RESOLVED INVALID
Severity:	major	CC:	x86-kernel
Priority:	High
Version:	unspecified
Hardware:	x86
OS:	Linux
Whiteboard:
Package list:		Runtime testing required:	---
Attachments:	Output of dmesg for the kernel built by the 1.8 genkernel Output of dmesg for the kernel built by the 3.0.1_beta6 genkernel

Description giovanni.bobbio 2004-01-17 07:45:52 UTC

When booting a kernel compiled with the 3.0.1 genkernels the keyboard and mouse are disabled when the USB and PCI hotplugging service is started.
The same kernel sources, with the same config files, work perfectly if compiled with genkernel 1.8.
Tested with the latest gentoo (2.4.22-r5) or ck sources (2.4.23-r1).

Reproducible: Always
Steps to Reproduce:

no way it could be genkernel's fault if the kernel config
and sources are the same. Just NOT possible.

I understand your point, still... I can reproduce this at will.
It may well be that I erred, or that the bug is not in genkernel, but I am not able to diagnose it any better.
Please follow my procedure and see if there's something horribly wrong. I list the history of what I've done:

cp -R linux-2.4.22-gentoo-r5/ linux-2.4.22-gentoo-r5-og
[Make a copy of the source tree, og for old genkernel]
vi /usr/portage/profiles/package.mask
[Mask genkernel 3.0.1]
emerge genkernel
[1.8 gets installed]
cp linux-2.4.22-gentoo-r5/.config /etc/kernels/config-2.4.22-gentoo-r5
ln -sf linux-2.4.22-gentoo-r5-og/ linux
genkernel
[Kernel with old genkernel is compiled]
vi /usr/portage/profiles/package.mask
[Remove mask]
emerge genkernel
[Re-emerge genkernel 3.0.1_beta6
rm linux
ln -s linux-2.4.22-gentoo-r5 linux
cp linux-2.4.22-gentoo-r5-og/.config /usr/share/genkernel/x86/kernel-config-2.4
[Copy the old config over the template]
genkernel --install all
diff linux-2.4.22-gentoo-r5/.config linux-2.4.22-gentoo-r5-og/.config
[Check that the config files are identical. They are.]
vi /boot/grub/grub.conf
[Set up grub appropriately]

Booting the two kernels produces the symptoms described in the original post.
I am attaching the dmesg output of the to boot procedures, and remain available to supply any other info you may judge relevant.
