I am unable to get a modem to work with PAO-960616 on top of 2.2-960612-SNAP in interrupt mode. I can get it working with poll I/O.

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.

When I start pccardd, I get the errors:

pccardd[162]: mem=d0000 pccardd[162]: Card "Cardinal Technologies" ("MVP288C2") matched "Cardinal
Technologies" ("MVP288C2") pccardd[162]: Using I/O addr 0x2f8, size 8 pccardd[162]: Setting config reg at offs 0x200 to 0x61 pccardd[162]: Reset time = 100 ms pccardd[162]: Assigning I/O window 0, start 0x2f8, size 0x8 flags 0x1 pccardd[162]: Assign sio1, io 0x2f8, mem 0x0, 0 bytes, irq 3, flags 80 /kernel: sio1: probe test 3 failed /kernel: Return IRQ=3 pccardd[162]: driver allocation failed for Cardinal Technologies

If I increase the reset time, I can get by the probe error sometimes:

pccardd[196]: Using I/O addr 0x2f8, size 8 pccardd[196]: Setting config reg at offs 0x200 to 0x61 pccardd[196]: Reset time = 10000 ms pccardd[196]: Assigning I/O window 0, start 0x2f8, size 0x8 flags 0x1 pccardd[196]: Assign sio1, io 0x2f8, mem 0x0, 0 bytes, irq 3, flags 80 /kernel: sio1: type 16550A /kernel: Slot 0, unfielded interrupt (3)

but the modem is still not usable.

Any ideas?
