Shame on me, sometimes it's really too > simple... This really works for FreeBSD 5.3-BETA5 of today, but it works *only* with IRQ 2/9. I also tried IRQ 5, which is not used by any other device (a least I couldn't find any notice about irq5 in the boot -v messages but for isic0), and this does not work with the same messages as with IRQ 10. Somehow I have the uncertain feeling that the new IRQ-Routing code has still some deficencies, at least for ISA-style IRQs... But it's no longer a severe problem for me, so I can follow RELENG_5 again. -- Ciao/BSD - Matthias Matthias Schuendehuette , Berlin (Germany) PGP-Key at and ID: 0xDDFB0A5F
