[DragonFlyBSD - Bug #2707] physical memory corruption with intel gpu 4500HD

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2707 has been updated by profmakx.


The reason for this is that we do not reserve memory in the IO memory rman on bootup. I have a patch for this, but it freezes the computer on boot at the moment, so it's useless as it is. It is basically a port from FreeBSD's nexus.c on amd64.

----------------------------------------
When running xorg, a memory corruption happens on the physical page at 0x80000000, leading to random crash depending on where the page is mapped.
Removing this page from the physical pool used by virtual memory makes the box stable.
