kernel

I used the script describe in this question to list the kernel installed on the computer :

How do I to remove or hide old kernel versions, to clean up the boot menu?

In the 3.2.0, I have 33, 34, 35, 36, 37, 38, 39, 41, 43, 44, 45 and 48. I would expect to be running 3.2.0-48 after a reboot, but I am still running 3.2.0-32. Why the kernels installed by auto update are not used?

[I am running 12.04 LTS]

/boot/grub/menu.lst was modified for the last time June 16 2013, it contains

3.2.0-32-generic
2.6.32-45-generic
2.6.32-44-generic
2.6.32-43-generic

A recovery for each of those and a memtest. I would have expected the kernel between 3.2.0-33 to 3.2.0-48 to be in this file before 3.2.0-32.

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
