I install OpenBSD on my Fastwell CPB905 Singleboard compter. IT have 4-RS-232 port on same IRQ, but on different address on isa bus. Then i setup only one port using configure command all ports work normally. But when i setup 2 of them in one boot configuration i get in dmesg: irq already in use. I found next thing in OpenBSD 3.8. documentation:
ISA devices can not share IRQs. If you find ISA devices sharing IRQs, you must correct this problem. But how it works on Linux & QNX? <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Без вирусов. www.avast.ru <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
