Details

Description:
In the kernel changelog (http://kernelnewbies.org/LinuxChanges), it is stated that a memtest built into the kernel should be started by adding the 'memtest' boot parameter. However this does not work on my system.

Additional info:
* package version(s)
kernel26 2.6.26.2-1



Steps to reproduce:
Boot with boot parameter 'memtest' and nothing happens...
This task depends upon

It's not enabled in the kernel. However, our installer CD contains memtest86+ and memtest itself is an installable package which is bootable from grub, so I wonder why we would need this.

In /proc/config.gz:
CONFIG_MEMTEST_BOOTPARAM=y
CONFIG_MEMTEST_BOOTPARAM_VALUE=0

so it should be enabled. I think it can come in handy when you do not have a CD at hand.

Just adding "memtest" won't work, you will have to give it a value, as 0 is the default which skips memtest.

Tested but did not work either.. (gave it value 4)

In 2.6.27:
# CONFIG_MEMTEST is not set
I don't see why we would want to enable it, it will only make the kernel bigger.
