Hi,
My laptop (thinkpad 570e) hangs hard straight after bringing up
interface with d-link dwl-650 wlan card. 2.5.73-bk1 works and
2.5.73-bk2 to 2.5.75-bk1 hang. If I boot without the card,
everything comes up, but inserting the card results to a hang.
Setting nmi_watchdog=2 has no effect.
So, what to try next?

Ok, bit more info: same thing happens with edimax 8139 based cardbus nic also. I've disabled apm and acpi from kernel and going to start going through the pci changes between 2.5.73-bk1 and bk2.

Its a hotplug/netdevice interaction, and it happens for many hotpluggable network devices, whether they be NE2K cards, wireless cards or whatever.

It was sent to Pat Mochel primerily for testing (since Pat was able to produce the feedback last time around to solve the problem.) However, I haven't heard back from Pat.

Developers don't have access to all possible combinations of hardware. However, the patch to ti113x.h came from 2.4-ac, and afaik there haven't been any reports of failure there.
