Mark IPW2100 as BROKEN: Fatal interrupt. Scheduling firmware restart.

[Evgeniy Polyakov <johnpol@2ka.mipt.ru>]

Hi.

Following bug exists in the ipw2100 driver/firmware for years and Intel
folks never responded to zillions bugzilla entries and forum notices in
the internet with some patch or firmware update (although did request
dmesg and debug info, and received them).

ipw2100: Fatal interrupt. Scheduling firmware restart.

I believe it is a firmware bug because after driver is unloaded and
loaded back again wireless adapter usually starts working (for small
amount of time though). My conspiracy feeling can suggest, that it may
be kind of a force to buy a new one, or trivial error in the firmware,
when it writes to the same place in the flash and essentially given cell
became dead or whatever else.

Intel folks, please fix this problem, I see no other way to force you to do
this than to mark ipw2100 driver as broken, since that is what it is.

Bug exists at least in .15 upto .24 kernels, just search above dmesg
line. I cought it with 2.6.24-19-386 ubuntu kernel, 1.3 firmware
version. lspci:

dmesg is pretty usual.
