xen 4.0.1/w 2.6.32 swapper: page allocation failure
hi
xen 4.0.1 w/2.6.32.41
Last week dom0 experienced an hard crash and box need to be restarted
manually (despite kernel.panic=20).
Serial console was not setup, only netconsole. No relevant entries through
netconsole, but analyzing logs I see some crashes twenty minutes before
fatal hang.

[LLVMdev] sys::MemoryFence() using __sync_synchronize() with GCC on ARM does not generate a memory fence
Andrew Haley brought up this interesting issue on the GCC mailing-list
that directly affect the stability of the ARM llvm target when using
multi-threading.
http://gcc.gnu.org/ml/gcc-patches/2009-08/msg00600.html
basically using __sync_synchronize() with GCC on ARM does not generate
any code for the fence.
For what I know:
The only working fix for this issue on Linux would be to create a call
to a high address Linux kernel helper named __kernel_dmb located at
0xffff0fa0 that performs the memory fence...
