What chipset are you using? Does the BIOS report more then 4-GB during boot? If it does, try this:

Phase 1:
1) type 'zypper in kernel-pae'
2) type 'zypper rm kernel-default'
3) type 'reboot'

Phase 2:
1) Type 'uname -a' and verify that the running kernel version has '-pae' after it instead of '-default'
2) Type 'asterisk-recompile' and follow the wizard
3) See if it lets you address more memory

Other then that, I don't have much else up my sleeve. I'm guessing that since it's only detecting 2-gigabytes of memory that you have either only 2-GB of memory installed or one of those infamous Intel chipsets that only address 2gb (Like the 945s). If it was the 32-bit memory limit (hence non-PAE) it would be 3.25GB or something like 3407872 KB or there abouts.

Best of luck either way.

Yep. You must also check the memory available in BIOS before it boots.

Kumba can't give you any more memory than the system believes it has physically in the machine.
