Re: [Ipw2100-devel] [ipw2200]Confirmation of power management problem

yes, nolapic in 2.6.9-rc3-bk8 works. I will bump my kernel and apply this 
patch unless its merged into -rc4? If not apply manually.

Len, great work on getting ibm-acpi into -mm. us ThinkPad users appreciate it!

This also solves the ipw2200 being stuck on during power off.
