- Why do I get interrupt conflicts with multi-port serial
- code?
-
-
-
- When I compile a kernel with multi-port serial code, it
- tells me that only the first port is probed and the rest
- skipped due to interrupt conflicts. How do I fix
- this?
-
- The problem here is that &os; has code built-in to keep
- the kernel from getting trashed due to hardware or software
- conflicts. The way to fix this is to leave out the IRQ
- settings on all but one port. Here is an example:
-
- #
-# Multiport high-speed serial line - 16550 UARTS
-#
-device sio2 at isa? port 0x2a0 tty irq 5 flags 0x501 vector siointr
-device sio3 at isa? port 0x2a8 tty flags 0x501 vector siointr
-device sio4 at isa? port 0x2b0 tty flags 0x501 vector siointr
-device sio5 at isa? port 0x2b8 tty flags 0x501 vector siointr

Why does every kernel I try to build fail to compile,
