Hi,
I'm running 4.2 with -current kernel on a centrino notebook with
Intel PRO/Wireless 2100 netword card. I installed ipw-firmware-1.3
but any attempt to configure the card freezes my system.
For instance, if I type

# /sbin/ifconfig -M ipw0

the system gets blocked in tsleep("ipwinit").

If I replace a call to tsleep in ipw_load_firmware with

        uint32_t mask = 0, term = IPW_INTR_FATAL_ERROR |
                IPW_INTR_PARITY_ERROR | IPW_INTR_FW_INIT_DONE;

        /* XXX: timeout */
        while( !(mask & term) )
                mask = CSR_READ_4(sc, IPW_CSR_INTR);

        return (mask & IPW_INTR_FW_INIT_DONE) ? 0 : ENODEV;

the system would block in tsleep("ipwcmd").

I looked at source code of linux ipw2100 project and I didn't like
the way they do it. I'm not a hardware developer, though.

I plan to continue looking into the problem but I need a direction
from experienced folks.
Thanks in advance,
