Hello everyone I am severely frustrated as I have built kernels in other distributions such as Slackware and Fedora but never had such greif as I am having with Ubuntu... Story goes I decided I will install Ubuntu 14.04 x64 anyhow as I am trying it out one of the things I like to do is build my own kernel from scratch from source code from Kernel.org anyhow im configuring and building my kernel no worries but when it comes to boot time I select my new kernel from the boot menu and it just hangs then drops down to a shell no errors nothing. I followed the information here and am still stuck some help would be greatly appreciated as this is really frustrating me otherwise my Ubuntu experience is quite enjoyable. Thanks in advance
I like to build my own kernels as I tend to get much better performance on my other distro's and I save a heap of RAM for example with a generica kernel and the Mate desktop environment with slackware 14.1 x64 on a generic kernel I use around 600Mb of ram with a custom built kernel I use only 250 Mb of ram its why I don't use generic kernels as I mentioned I get better performance especially out of my older machines never had this trouble with Slackware or Fedora anyhow I may be onto the problem I am compiling a kernel now I will report back if I have fixed the issue and what caused it
Here is a image that might shed some light on the subject I never had this issue with Slackware or even FreeBSD I thought i'd give Ubuntu a whirl but it uses way too much resources and is quite sluggish so I thought I will do what I do with all my other Linux Os's is compile a kernel and that is where I get most of my performance gain just in that but anyhow hope this may give someone a clue that I can't work out
I just want to show this is my Slackware 14.1 x64 system with the mate Desktop environment on idle this is really good even when I was running with KDE i was getting around 300Mb idle so with Ubuntu I should get rougly the same with just the kernel built the way I like it http://i76.photobucket.com/albums/j1...pseb8d91a7.png
Do you still have old generic kernel/initramfs at /boot directory and menuentry in Grub menu for this old kernel?
If so you could compare this old menuentry and new one for possible difference.
I got my .config from the generic installed kernel I did the same mods as I did when I did make xconfig as I do when I make my Slackware kernels I even tried a default .config that come with the stock kernel from kernel.org and no luck it is really frustrating I have been a bit busy and am still researching and trying to work out where it is going wrong I am careful not to exclude sata or even scsi and ide drivers I will go through and compare I didn't think of comparing I must of accidently un checked a driver as I noticed on the bootup of the single user mode kernel it stops just after usb devices that is where it stops not that it will be much help I will keep hacking away and will see if i can provide some more info it is really frustrating that is for sure
Actually wondering if I could use my .config from my Slackware kernel that works fine if that might work? as that is working perfect and that is how I got my system running so efficient on resources ?
since you are having trouble I suggest you start with the config from a standard Ubuntu kernel for your system, the kernel source from the Ubuntu linux-source package and to use the make-kpkg method. Once you have established that you can get to work you might consider using the upstream source from kernel.org. I'm not sure how heavily Ubuntu patches their kernels and what if anything in their userland depends on those patches.
I think that might be my only option I have been having great success with slackware for a long long time using the upstream kernels I even use rc kernels just for fun and no issue but for some reason it refuses to work for me so I might have to take your advice and give that a go and sit back and work out where my problem has been thank you for the suggestion it has been a frustrating few days I am familiar with Ubuntu butI have been using slackware for many many years and I only play around with Ubuntu as I like to test out other distros or for this case I am installing Ubuntu as it works well with my Android.... All good thanks I will use the standard Ubuntu kernels and work with that for the moment Cheers
