The amount of expanded memory required to set up your XPRAM partitions
depends on the 'sizes' parameter specified for the xpram module or on
the specifications for the 'xpram.parts' parameter if the XPRAM device
driver has been compiled into the kernel. Your
current specification exceed the amount of available expanded memory.
Your XPRAM partitions are probably not configured as intended.
User response
If the XPRAM device driver has been compiled as a separate module,
unload the xpram module and load it again with an appropriate value
for the 'sizes' module parameter. If the XPRAM device driver has been
compiled into the kernel, adjust the 'xpram.parts' parameter in the
kernel command line and restart Linux. If you need more than the
available expanded memory, increase the expanded memory allocation for
your virtual hardware or LPAR.
