[dm-devel] Re: Bug#403426: kernel corrupts LUKS partition header on arm

Martin, I wonder if this has anything to do with the virtual memory
bug in the kernel that we experienced with apt. It could be that this
bug existed before 2.6.19 but was much harder to trigger (e.g. see
http://lkml.org/lkml/2007/1/3/285). It would be interesting to try
accessing a LUKS partition under heavy load while running 2.6.20-git,
but that will have to wait until the weekend for me to test it.

Ok, I tested 2.6.19-1~experimental.1 +

  vm-fix-nasty-and-subtle-race-in-shared-mmap-ed-page-writeback.patch
  flush_anon_page-generic.patch
  flush_anon_page-arm.patch

and I am still unable to access the LUKS paritition under heavy load
and swapping, so it appears that there is someting else causing this
problem.
