Hi, I'm happy to ask developers for help , I'm really confused for my crash error.<br><br>My computer room is running 60 nodes,OS: suse 11 sp1 x86_64 Kernel:2.6.32.12-0.7-default Crash:crash-5.0.1-1.5.5<br><br>recently , server often kernel crash, Kdump service dump the vmcore in /var/crash/happen-date/vmcore,<br>
<br>I installed the kernel-debuginfo so that check out why crash ,but I got this:<br><br><br><br> linux:~/bb # crash -d8 vmlinux-2.6.32.12-0.7-default vmlinux-2.6.32.12-0.7-default.debug vmcore<br><br>crash 5.0.1<br>Copyright (C) 2002-2010 Red Hat, Inc.<br>

<br>something like crash can't find cpu_possible_mask and cpu_possible_mask in vmcore I guess,<br><br>I Google it and find some email talking about this , read the whitepaper writed by anderson, but I can't resolve it.<br>
