[Julien Kirmaier <julien.kirmaier@gmail.com>]

Dear kernel maintainers,

  while processing with gs rather large postscript files (~1Go) the kernel 
pulled this message in the console:

  The machine did not halt after this message as it did two weeks ago. I 
thought at the time that bad RAM was involved so I replaced it; memtest86 
did not return anything wrong with the new 1Go RAM module.

  I'm running 2.6.18 vanilla kernel on Debian Sarge, raid-1 software, the 
swap space is also on raid1.

  Tell me if you need more informations (or to whom I should address this
message if linux.kernel is not relevant).

  Sincerely,

JKr
