Description Guy Streeter 2007-05-30 19:23:01 UTC 
The "crash" kernel module is needed in order for the crash program to work on a
live system with more than 896MB memory.
We need CONFIG_CRASH=m in all our configs.
Comment 1 Guy Streeter 2007-05-30 19:53:00 UTC 
It's worse than just the CONFIG setting. The crash driver is a RHEL5 add-on.
Comment 2 Guy Streeter 2007-05-30 20:42:39 UTC 
I think this doesn't affect x86_64, at least not at the same low memory size.
It it really a problem for i686.
Comment 3 Guy Streeter 2007-06-08 16:38:02 UTC 
x86_64 doesn't have the memory limit, so we only need the /dev/crash driver for
i686.
Comment 4 Guy Streeter 2007-06-19 18:41:35 UTC 
I've done my part on this one. It's up to Clark now.

you need to apply this patch, and set CONFIG_CRASH=m on i686 and not set it on
x86_64.

This will go into next release (>= 2.6.21-32)
