I think that kdump is what you want, it doesn't work with suspend but it should work in your case. There's a wiki entry on it as well, it works with kexec to load a new kernel when the running one crashes. If that fails you'll need to use a debug kernel and kdb.
I don't understand. I have read the article, if it is http://en.opensuse.org/Kdump It says: 1. Add the crashkernel=size@offset option to your bootloader configuration. See the table below for recommended options for the different architectures. Then reboot. 2. Load the panic kernel with kexec -p vmlinuz --append="command_line" --initrd="initrd". The command line should include the root file system (root=), the irqpoll and reset_devices options and should end with the runlevel you would like to have in the kdump environment (preferably 1). 3. Now crash the kernel, for testing you can use Sysrq-c. 4. In the kdump environment, copy /proc/vmcore away. 5. Reboot. Step 1. Where exactly do I add the "crashkernel=64M@16M" option? Here, inside the kernel line? ###Don't change this comment - YaST2 identifier: Original name: linux### title openSUSE 11.1 Beta 5.2 - 2.6.27.7-3 root (hd0,7) kernel /vmlinuz-2.6.27.7-3-pae root=/dev/disk/by-label/160_test resume=/dev/disk/by-label/320_swap splash=silent showopts vga=0x317 initrd /initrd-2.6.27.7-3-pae Step 2. Does it means that I have to manually boot the panic kernel? In a text console, or how? What exact command do I have to type? Where? I don't understand that paragraph, to me is like reading chinese. Step 4. When the kernel freezes, ¿how do I go to the kdump environment? The kernel is frozen, nothing works. No keyboard. How do I go to that kernel? What commands do I have available? How do I "copy /proc/vmcore away"? To where? The system is frozen. That kernel only has 64mb, I assume I will not have a "dd" command, I suppose. I'm sorry, all that kdump thing looks very nice, but is only usable by people that already know how to make use of it or are kernel devs. I don't know how to use all that. I just want to provide the bugzilla kernel people the information they request, I'm not a dev. And they don't help at all :-( As it is, I'll have to wait till some big somebody has a problem and steps in. Meanwhile, I'l have to wait till 11.2. - -- Cheers, Carlos E.
