Re: [Crash-utility] How does crash find booted kernel?
Hi Buland,
Thanks very much for your answer! After installing the right debuginfo package,
now crash works!
BTW, if possible, could you spare a little time to explain other
confusion: it seems
that I don't select whether "debug" version or not during install RHEL
7, why does it
install the "debug" version for me? Thanks!
Best Regards
Nan Xiao

Nan,
The kernel running on your system is kernel-debug-3.10.0-123.el7.x86_64
[root@localhost ktap]# uname -r
3.10.0-123.el7.x86_64.debug
^
'....
It is provided by kernel-debug-3.10.0-123.el7.x86_64.rpm
The kernel-debuginfo package installed on your system is for normal kernel.
[root@localhost ktap]# rpm -q kernel-debuginfo
kernel-debuginfo-3.10.0-123.el7.x86_64
To fix it, you need to install
kernel-debug-debuginfo-3.10.0-123.el7.x86_64.rpm
