ARM Paging Problems

Hello,
I'm experiencing a paging problem.


I'm playing around with an ARM LH7A404 machine, using a flash memory module
as a file system (mapped using JFFS2)


I've recently upgraded the single RAM module at bank-0 from 32 MB to 64 MB,
as well as the flash module from 16MB to 32MB.


Now I'm experiencing bad page states when the busy-box /sbin/init runs.


The following is a snippet of the last entry's before the kernel panicked.


----------------------------------------------------------------------------------------------------------------------------------------------------

Configure Core FPGA...
Done!
Init LCD.
binFileRead: Cannot open file "/.sw_ver".
Run "/sbin/init"!!!<0>Bad page state at free_hot_cold_page (in process
'init', page c02192a0)
flags:0x00000000 mapping:00000000 mapcount:-1 count:0
Backtrace:
Trying to fix it up, but a reboot is needed
Inconsistency detKernel panic - not syncing: Attempted to kill init!
ected by ld.so: d ynamic-link.h: 122: elf_get_dynamic_info: Assertion
`info[20]->d_un.d_val == 17 || info[20]->d_un.d_val == 7' failed!

----------------------------------------------------------------------------------------------------------------------------------------------------


I'm also loading the kernel at a different location than the default
settings:

CONFIG_ATAG=y
CONFIG_DISABLE_MMU_AT_BOOT=y
CONFIG_ATAG_PHYS=0xc0000100
CONFIG_APEX_VMA=0xcd000000
CONFIG_KERNEL_LMA=0xc1000000
CONFIG_SDRAM_BANK0=y



I've been investigating the issue and I'm at a loss. It seems like a memory
mapping issue but I cannot say for certain. Is there something I'm
overlooking?


I have checked the memory modules and they are working as expected.
