Description Guy Streeter 2007-05-30 15:23:01 EDT
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 15:53:00 EDT
It's worse than just the CONFIG setting. The crash driver is a RHEL5 add-on.
Comment 2 Guy Streeter 2007-05-30 16:42:39 EDT
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 12:38:02 EDT
x86_64 doesn't have the memory limit, so we only need the /dev/crash driver for
Comment 4 Guy Streeter 2007-06-19 14:41:35 EDT
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

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