  <H2><A NAME="11"></A>11. Other problems</H2>
<p>Some accelerated drivers may cause the machine to lockup when starting
up the server on some versions of SVR4.0.  The problem seems to be
related to the kernel checking for the presence of physical memory
when mmaping /dev/pmem.  This can cause problems when mapping memory
mapped registers.  This was known to be a problem with the MGA driver in
the SVGA server.  Some other drivers may be affected too.  The problem with
the MGA driver is now fixed.</p>
