Bug#684352: HP Pavilion dv4000: Wifi kill switch always on unless ACPI=off is used



Also note that my PC is a Compaq Presario V4000T, it shares a lot of the same hardware as the HP Pavillion DV4000, but there are some hardware differences\.  They *might* be using the same BIOS,, I really don't know.  They do share the same service/repair manual but they have different replacement part#s.

Not sure if that's important for you or not.

Thanks for reporting it, and sorry for the slow response.

Some ideas:

 - please attach "acpidump" output.
 - am I correct in imagining 3.5.y from experimental behaves the same way?
 - does the squeeze (2.6.32.y) kernel avoid trouble?  It should work fine
   on a wheezy/sid system.

Next step will be to take this upstream, but let's try to figure out
what caused the regression (e.g., which subsystem) first.

Hope that helps,
Jonathan
