ndis0: acpi issues and interrupt storms

[Lukas Ertl]

Hello,

using ndis0 causes some issues on a -CURRENT from yesterday, although the 
problems have been there for several weeks now:

*) I'm seeing frequent interrupt storms on ndis0:

Interrupt storm detected on "irq6: ndis0 uhci2"; throttling interrupt source

By setting hw.intr_storm_threshold=10000 I can use the card, but as soon 
as I "ifconfig ndis0 down", the storm happens again, and the ifconfig 
process hangs.  I also tried removing the USB bits from if_ndis.ko and 
ndis.ko, but that didn't change the situation.

*) ACPI power off won't work if the ndis0 interface is up, the shutdown 
process hangs after the final "Uptime: ..." output.  If I then push the 
power button, I get an "acpi: suspend request ignored (not ready yet)" 
message.  Note that this _only_ happens if ndis0 is up.  If the interface 
is down the machine powers off as expected.

I'm using a IBM Thinkpad T42p with the latest .sys and .inf from the IBM 
website, the card is an Intel PRO/Wireless 2100.

cheers,
le
