Mark Diekhans stands accused of saying:
The same results occur with two difference modems, one of which is on the supported car list (Megahertz XJ2288). I suspect this is either a configuration mistake or a problem with pcic or sio drivers:
/kernel: PC-Card Cirrus Logic PD6710 (5 mem & 2 I/O windows) /kernel: pcic: controller irq 10 /kernel: sio0 at 0x3f8-0x3ff irq 4 on isa /kernel: sio0: type 16550A /kernel: sio1 not found at 0x2f8
WHen the kernel is booting I get the message: /kernel: sio0: 64 events for device with no tp
although there is not device attached to sio0.
This sounds like the card doesn't have a 'real' UART in it, but rather a micro pretending to be one. This is pretty tragic.
You could look the places in sioprobe() where the EXTRA DELAY comments are, and try adding 'DELAY(500)' in these places.
/kernel: sio1: probe test 3 failed
The card failed to generate an interrupt when it should have.
/kernel: sio1: type 16550A /kernel: Slot 0, unfielded interrupt (3)
... but it's generated it later.
