Hello,
I've been testing 2.6 and SKAS and receive the following BUG on both 2.6.2 and
2.6.3. Patches applied are (in order):
*
http://www.user-mode-linux.org/~blaisorblade/patches/2.6.2-v1/uml-patch-2.6.2-0.bz2
* http://www.user-mode-linux.org/~blaisorblade/patches/2.6.2-v1/00-Combo-v1.bz2
*
http://www.user-mode-linux.org/~blaisorblade/patches/2.6.2-v1-host-skas2/00-2.6.2-v1-host-SKAS2.patch.bz2
* the CFQ patch from the -mm tree
* patch-2.6.3 (only on the 2.6.3 kernel, obviously)
kernel BUG at include/asm/mmu_context.h:53!

Does this look like it could be caused by the SKAS patches, or would you suspect
the CFQ patch? The box seems to run fine, but once I fire up a few UMLs and
start
banging around, the host will BUG.
Thanks,
-Chris
