I am using Ubuntu 11.10 32 bit on notebook core 2 duo, 4GiB RAM. In order Ubuntu to detect and use more than 3GiB RAM, I apt-get PAE Kernel. The problem comes when there were two update of kernel, linux-generic kernel and linux-generic-pae.

Should I update linux-generic-pae kernel only? if the answer yes, how to stop update notification of linux-generic kernel?

My server crashed without any warning. Looking in var/log/messages, I found the following:

Code: Aug 14 14:23:36 server kernel: Call Trace: Aug 14 14:23:36 server kernel:  [<c0167fbf>] T.648+0x55/0x15f Aug 14 14:23:36 server kernel:  [<c0405b3d>] ? _raw_spin_unlock_irqrestore+0xf/0x11 Aug 14 14:23:36 server kernel:  [<c02a3fbd>] ?

I run dist-upgrade and I ended up with this error:

Error!

I'm currently having to recompile my wireless driver from source every time I get a new kernel release. Thinking it would be awesomely hackerish to automate this process, I symlinked my Bash build script to /etc/kernel/postinst.d.

I'm running Ubuntu 11.10, which came with kernel version 3.0.0-14. I downloaded and built a kernel from the 3.1.0 branch. After installing the new kernel, I see that my /boot/initrd.img-3.1.0 file is HUGE. It's 114MB, while my /boot/initrd.img-3.0.0-14-generic is about 13MB. I want to get rid of the bloat, which is clearly unnecessary.

Hi can some one help me in understanding this.

On Centos 6.2 its showing kernel as 2.6.32-220.el6.x86_64

whereas on Ubuntu 12.04 its showing as 3.2.0-23-generic.

3.0 kernel is one of the latest kernel and Ubuntu is using that, whereas Centos is using an old kernel. Why is it so?

Can an old kernel offer every new feature that a new kernel can? Why aren't they upgrading to 3.0?

Hi,On cent os 6.0 (64bit) installed machine with kernel 2.6.32-71 we are seeing continous kernel stack trace and machine is not getting accessed by ssh after stack trace on terminal.

One of our production clusters driven by XCP suddenly went uresponsive.

I just removed old kernel version using ubuntu tweak., I wonder why my grub default is Kernel: 3.2.0-34-virtual rather than Kernel: 3.2.0-34-generic, but when I change my grub default to Kernel: 3.2.0-34-generic my network connection lost. Did I missed something?
