You'll have to manually reboot the machine...but the problem is that you
need to upgrade the kernel first.  What has happened is that all of the
syscall numbers have changed from 1.2 to 1.3 (well, many of them), so the
newer binaries cannot interface with the older kernel.  Once you install a
1.3 kernel, everything should be just fine.

I hope this helps.

Later.
