Post Kernel Upgrade Problems
I installed the 3.2 liquorix kernel from the repos, but I can't get the bot from it. I ran the following command:
Code:
[root@HPDV4 Scott]# update-initramfs -c -t -k 3.2.0-2.dmz.1-liquorix-amd64
update-initramfs: Generating /boot/initrd.img-3.2.0-2.dmz.1-liquorix-amd64
[root@HPDV4 Scott]#


and I don't get any errors.

I have not changed anything in the GRUB menu. It is a dual boot laptop. M11 upgraded to KDE 4.7.4.

Any pointers much appreciated.

What's the GRUB entry for that kernel?

Sounds like using the 'newest kernel' entry. Is that the case?

Thats the same code given to me by stevo when I upgraded to 3.2. ( minus the T flag ). Perhaps you need to reinstall grub.

I tried to add vmlinux-3.2.0-2.dmz.1-liquorix.amd64 to the boot line, but it booted then hung, saying it could not find /dev/sda5

I wonder, were the vmlinuz and initrd.img symlinks created for the liquorix kernel?

What does the following show?
Code:
ls -l /boot # the "-l" is a lowercase L

You need to create vmlinuz and initrd.img links to /boot/vmlinuz-3.2.0-2.dmz.1-liquorix-amd64 and /boot/initrd.img-3.2.0-2.dmz.1-liquorix-amd64

Or add an entry in menu.lst like this

Code:
title MEPIS 11 at sda5, liquorix kernel
root (hd0,4)
kernel /boot/vmlinuz-3.2.0-2.dmz.1-liquorix-amd64 root=/dev/sda5 nomce quiet splash vga=788 xdrvr=intel confx
initrd /boot/initrd.img-3.2.0-2.dmz.1-liquorix-amd64
boot

The symlinks weren't created when the liquorix kernel was installed.

You would create them by running the following root commands:
Code:
ln -sf /boot/vmlinuz-3.2.0-2.dmz.1-liquorix-amd64 /boot/vmlinuz
Code:
ln -sf /boot/initrd.img-3.2.0-2.dmz.1-liquorix-amd64 /boot/initrd.img

After you create those symlinks the "MEPIS 11 at sda5, newest kernel" grub menu entry should boot the liquorix kernel. The entry that follows it should still boot the original 2.6.36-1-mepis64-smp kernel.

@kmathern,
That worked, boots to the new kernel. It lost the wifi upon rebooting. I'll play with it and see what happens.

EDIT: Changes the interface from eth1 to wlan0 in wicd and wifi connected right away.
