Description Jeff Layton 2006-01-17 21:10:14 UTC
dump_stack() isn't implemented on x86_64. Trying to call it from a module gives
an error message like this:

This architecture does not implement dump_stack()

This is not a "bug" per-se, but it does mean that x86_64 lacks a debugging tool
that can be very nice to have (triggering a stack dump on a certain condition
from a module).

patch to add dump_stack functionality to x86_64

This patch corrected this problem on my test rig.

simple kernel module that demonstrates problem

This is a simple kernel module that simply does a dump_stack in the init phase.
This can be used to demonstrate the problem (and test the patch).

Comment 3 Ernie Petrides 2006-02-24 03:44:19 UTC
A fix for this problem has just been committed to the RHEL3 U8
patch pool this evening (in kernel version 2.4.21-40.3.EL).

Comment 4 Ernie Petrides 2006-04-28 21:45:44 UTC
Adding a couple dozen bugs to CanFix list so I can complete the stupid advisory.
