>Description:
The lm(4) driver does not identify the LM81 chip at attach time.  This
does not prevent it from working, though:

>How-To-Repeat:
Boot a kernel configured with

lm0 at isa? port 0x290

on a system with Iwill BD100 motherboard.  Notice that

lm0 at isa0 port 0x290-0x297: Unknow chip (ID 128)

is printed at boot time.
