[-- Attachment #1 --] I have 2 Asus A8V motherboards running FreeBSD 6.0 and 6.1 (amd64) and I see the following in dmesg.. sio0: configured irq 3 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: <16550A-compatible COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on acpi0 sio0: type 16550A sio1: configured irq 4 not in bitmap of probed irqs 0 sio1: port may not be enabled sio1: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 on acpi0 sio1: type 16550A The ports are enabled in the BIOS and do seem to work.. mostly. I have had odd problems trying to talk to stuff connected to the on occasion though. I have another [custom] driver that is based on sio.c and it shows the same warning (it is a PCI RS485 card). I have tried playing with various ACPI & ATPIC settings in the BIOS but no change. If I disable ACPI in the kernel the IDE driver fails to activate it's IRQ and then panics a bit later... I have updated to the latest BIOS but it had made no change. Hmm actually I just looked through the code.. It appears that this happens because isa_irq_pending() is a noop unless isa is in the kernel, and it isn't in GENERIC. Perhaps those tests in sio.c should be conditionalised on isa too? -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (FreeBSD) iD8DBQBEmiJ25ZPcIHs/zowRAv0uAJ4qUTEo0pMnw3tOFOpP49Vsj5n5mACgkiUT 81ue+TGFGKtpPLkkvU4ynbU= =c15Q -----END PGP SIGNATURE-----
