Are there any known problems with the ACPI C3 power saving state? Everything
works fine now, as long as I disable the C3 power saving state. If I enable
it, the machine locks up as soon as I access the net.
I did not find any precautions concerning power management in the wi(4)
driver, but it does not use DMA, whereas ipw
(http://www.ecademix.com/JohannesHofmann/ipw-dragonfly-1.4.tar.gz) does.
Perhaps this has to do with the problem?
