Hi, I am trying to use kexec and kdump together and everything seems (!) to work fine if I give kexec a lot of memory (crashkernel=100MB at 16MB). If I lower the size of the preallocated memory then the original kernel keeps crashing during booting with random errors right after the bootup script started kexec. The oops are probably caused by some kind of memory corruption. This made me thinking. How should I choose the size of the reserved memory and how can I be sure that it is 'stable' and nothing corrupted the kernel memory ? Thanks in advance. Best regards, Laszlo Benedek p.s.: Can I search in archives of this mailing list? I failed to find it but I hope it exists somewhere.
