AFAIR ia64 uses 8K pages.

Please do the following:
1. apply the patch at the end of this message, reproduce the problem
and show me both exact panic message from the patched kernel and 'show
pginfo addr' again.
2. show me the ls -la <file> output for the file which was accessed
through nginx, also what is the filesystem where the file resides on ?
