I have an mpc8378 system with 512MB ram and 256MB flash (NOR). When I start the
system I get the infamous message vmalloc failure. If I do cat /proc/meminfo I
can see that I have only 212MB of VMALLOC space.
I tried the advanced options and change the KERNEL_START to 0xb0000000 (instead
of 0xc0000000), however after doing that the system became unstable with
crashes left and right.
The current work around is to set the command line mem=400M, however I like to
use the whole RAM. What are the possible culprits that made my system unstable
when making the KERNEL address space larger ?. Can it be because of PCIEs
devices, I see that the PCIE memory is mapped to 0xa000000/0xc0000000.
Regards,
R.
