Description arjan 2000-06-14 08:40:01 UTC

The Cylcom YeP device driver has a problem with registering the devices for the second and futher boards
Either the MAKEDEV script or the syscalls to 'make_dev (..)' in cy.c should be changed.

Fix: 

the second arg in make_dev should be something like this :
( adapter * 65536 + ( unit % CY_MAX_PORTS ) )
How-To-Repeat: Just install more than one YeP board and rebuild a kernel supporting both board. Try to connect to a port on the second board.
example : cu -l /dev/cuac10

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?

I still had to change the lines in the cy driver the last time I updated the particular
systems to 4.3 stable about 2 weeks ago, so I guess the answer is YES.
