RE: [uml-devel] SKAS on AMD 64-Bit

["Anthony Brock" <brocka@sterlingcgi.com>]

Given a lack of responses to my inquiry, I've attempted to migrate the
existing patches to the "arch/i386" and "include/asm-i386" directories to
the corresponding "arch/x86_64" and "include/asm-x86_64" directories.

However, I am experiencing the following issue during boot of a previously
functional guest UML when I use the new Host Kernel:

Checking for the skas3 patch in the host...found
Checking for /proc/mm...found

Kernel panic: kernel BUG at mm/mmap.c:700!


Any ideas? How would I generate a backtrace for this issue?

I am attaching a copy of the non-functional patch. This patch applies
against a vanilla 2.6.7 kernel with host-skas3-2.6.7-v1.patch pre-applied
(in other words, it's a patch to the SKAS3 patch). Thanks in advance!

Tony
