KDB is a wonderful tool, but I am having problems using the version shipped
with
the linux-2.4.18-18SGI_XFS_1.2pre5 kernel (out of the XFS project at
oss.sgi.com).
First, I am not getting any symbols out of the stack backtraces.
Second, I am not able to break into a system hang - making the debugger
useless for what I really need it for.
In previous versions (namely, linux-2.4.18-4SGI_XFS_1.1) I was able to fix the
break-in problem by applying an apic patch that distributed interrupts so that
everything was not going through CPU0. This patch does not work with the
2.4.18-18 Red Hat kernel, though...... so.....
Is there any new patch recommended to help debug CPU0 hangs on the
Red Hat 2.4.18 (current) distributions ?
Is there anything I need to do special to get symbols in the KDB tracebacks
(like configure in stack frame pointers, maybe?) ?
Is there anything that anyone could recommend that I read which would
help me figure this stuff out ?
Thanks,
Jim Foris
