Lots of people have problems with new kernels. it so easy.. here you can find the original link. I have AMD 1400CPU , so I am going to install the k7 version apt-get install kernel-image-2.6.8-3-k7 search for the kernel like this: apt-cache search kernel-image-2.6 and dont forget to update your initrd file if you use md devices and raid, on your root device, check if you do. first put the modules for /etc/modules in the /etc/mkinitrd/modules cat /etc/modules >> /etc/mkinitrd/modules lsmod | grep raid if you see md and/or raid add the lines to /etc/mkinitrd/modules raid1 md check which kernel libaries are on your system here: ls /lib/modules on my system gives 2.6.8-3-k7 2.4.18-bf2.4 2.4.27-10-hpt i was running kernel 2.4.27-10-hpt now but we need the modules from the new kernel. now make a new initrd: -o for the ouput file and then the kernel version. mkinitrd -o /boot/initrd.imd-2.6.8-3-k7 2.6.8-3-k7 and update grup : update-grub reboot your server. if your server doesn't boot, reboot with the old kernel and run lsmod again and check for other modules. sugestions or improvements send then to me. email@example.com , thanx.
