HD 3450 incredibly hot when idle using RadeonHD

[tom66]

I ran the commands:

cd /boot
sudo update-initramfs -u vmlinuz-2.6.34-rc4
sudo update-grub

But 2.6.34 will not start; 2.6.32 still runs fine.

thats not what i told you, correct way:

sudo update-initramfs -uk 2.6.34-rc4
sudo update-grub

thats not what i told you, correct way:

sudo update-initramfs -uk 2.6.34-rc4
sudo update-grub

I got an error with the first command:

thomas@jupiter:~$ sudo update-initramfs -uk 2.6.34-rc4
update-initramfs: Generating /boot/initrd.img-2.6.34-rc4
Cannot find /lib/modules/2.6.34-rc4
update-initramfs: failed for /boot/initrd.img-2.6.34-rc4

I looked in /lib/modules and only 2.6.32-19-generic is there - have I missed something out in the build process?

run:
make modules_install

on the kernel sources

Won't boot. Doesn't kernel panic, but drops me to a busybox shell complaining root device not found. It said to check cat /proc/modules; it is empty, and I can't see any disk drives in /dev. I tried with both the UUID and /dev/sda6.

Thanks.

Anybody? I must have missed something out in the build process because last time I built a kernel I just ran make menuconfig, make, make install and it worked. Sorry for seeming so newbish, but I don't know why it isn't working.

Thanks.

Try grabbing a kernel from here.

http://kernel.ubuntu.com/~kernel-ppa/mainline/

They've also got debs of drm-next if you like.

+1 to everyone who's helped, I think it's working. I've got 2.6.34 on here from the deb that was suggested, which was easier than compiling (just double click...)

I'll have to do some more tests, but the GPU is staying in the 60-65?C range, which although hotter than fglrx, is not 95?C and melting the GPU! (The temperature changes depending on the workload - playing with Compiz makes it hit 68?C.) Plus I still get all the benefits of radeon non-user modesetting: nicer terminals, nicer and faster boot/shutdown, screen capture.

Thanks again. I'm now happy(ier) with Ubuntu.
