Subject: sio interrupt problems with PAO-960616 [pccard-test]
Sender: owner-mobile@freebsd.org
X-Loop: FreeBSD.org
Precedence: bulk


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?
