Hi Kernel alias,
I am a newbie and I am trying to figure out ways where in I can recover the Linux in below two scenarios: 1. my specific process hangs. 2. kernel gets hung partially or completely.
I have done some reading and seems like there is softlockup and hardlockup mechanisms in Linux source base that I can use but not sure, if yes I have below questions: 1. Which kernel version is minimum required for this? 2. How do I know that soft and hard lockup are enabled in my kernel? 3. How can I customize the behavior of default action that been taken? 4. Can I use these two lockup mechanism to find out if my process is hung or not? 5. Any pointers to any docs that can help will be appreciated.
I will greatly appreciate any help here.
What about crashing the system using sysrq and analysing the ramdump using crash utility? May be the following link give you some pointers, https://wiki.ubuntu.com/Kernel/CrashdumpRecipe Thanks, Arun
