   You don't need bounce buffers support, so you may as well kill this option.

   Actually, that's not what that option does. It adds some additional
diagnostic code which may or may not be well tested. This option is only
recommended for kernel developers who understand the ramifications of
using it.

>options         "MAX_USERS=300"

   That's not a real option.

   The 3c905 (vx) driver has been in various states of working/not working.
If it is possible for you to try, you may wish to swap this out for a DEC
chip based card or an Intel Pro/100B.
   It would be useful if you could add options "DDB" to your kernel. You can
then escape to the debugger (ctrl-print_scrn) and do a "ps" to look at the
process states - the WMESG should be useful in determining why things are
hanging.
