Hi, I am using custom 460ex board with kernel version 2.6.30. I noticed that page_alloc() is returning a page whose memory is already allocated by lmb_alloc() while unflattening the device tree. As per my knowledge the memory allocated by lmb_alloc() should be reserved till the end, right? Some mo

Kernel cannot see PCI device on 460EX
