Description

When starting a VirtualBox virtual machine with Linux 2.6.29-rc4 as the host kernel, I'm getting this kernel warning showing up:

This is this warning:

	if (is_ram != 0) {
		/*
		 * For mapping RAM pages, drivers need to call
		 * set_memory_[uc|wc|wb] directly, for reserve and free, before
		 * setting up the PTE.
		 */
		WARN_ON_ONCE(1);
		return 0;
	}

Still a problem in VirtualBox 2.1.4.

comment:3 Changed 5 years ago by robhancock

With 2.6.29-rc6 I get the problem described here:

 http://www.virtualbox.org/ticket/3403

The solution of uncommenting

# VBOX_USE_INSERT_PAGE = 1

in /usr/src/vboxdrv*/Makefile appears to resolve both issues.
