Kexec, I have been experiencing the crash below on Ubuntu 10.04 running 2.6.32-34-server and 2.6.38-8-server as the crashkernel on X86_64. The tools are: kexec-tools 1:2.0.2-1ubuntu3 makedumpfile 1.3.7-2 kdump-tools 1.3.7-2 I would be interested to know if this is a known problem and if so whether or not there is a patch in the pipeline to correct the problem. I will be happy to provide any other details that are required including debug builds if necessary. Tim Hartrick EdgeCast Networks, Inc.
