Try upping your kernel's vmalloc space

1. cat /proc/meminfo | grep -i vmalloc

Observe the vmalloctotal you have and convert from kB to MB.

2. Add a vmalloc=NNN to your kernel commandline on boot.  NNN should be the number of megabytes of address space to allow.  Try 64 or 128 megabytes more than your current setting.

Regards,
Andy
