init (busybox) problem on OSK5912

[Eduardo Gallofin <egallofin@yahoo.com>]

Hi Andrzej,

   Thanks for your response. However, we already have
swap support enabled all the time, but still the
problem persists. And it does not seem random at all,
our applications always fail with a segfault when
connecting or binding to a socket....

   I'm using the tool chain available at the
linux.omap website (3.3.2).... I've tried 3.4.1 but I
still have the same problem... do you have a link to
the newest toolchain (binaries please). It might be
worth a try... 

   Thank you very much!
