For the default 4K pages, my 2.6.11 kernel compiles and boots just fine. I want to re-build it with large pages, to improve my application performance. I tried modifying PAGE_SHIFT in "page.h" to 13 (8K pages) and re-build my kernel. Compilation worked out fine, but my kernel does NOT boot, nor it prints anything to the console. Has anyone successfully compiled & booted a 2.6 kernel with pages larger than 4K ? What am I doing wrong ? Thanks a lot. _________________________________________________________________ Express yourself instantly with MSN Messenger!
