unable to handle kernel paging request at virtual address
I am getting the following error after our system has been running for between 4 and 16 hours:
[19246.579251] BUG: unable to handle kernel paging request at virtual address 00002d87
[19246.587247] printing eip:

Any ideas of how we can debug this? We are building the kernel ourselves for a custom embedded platform. The platform with the same kernel, but a different application works perfectly fine. We have also run memtest x86 overnight.
Thanks in advance!
