If the machine is crashing, you have a serious kernel and/or hardware
issue. Subversion should *not* be able to crash the host, especially
if it is not running as a root user.

Why would you be afraid to re-install the Subversion software? And why
do you think it would help? Can you boot with an older kernel, of
which the last 2 or so should still be available at boot time, and see
if that helps? Is this real hardware, or a virtualized host on some
instance that may be incompatible with the latest kernel?
