Hi,
When I enable the iwlwifi power management feature, my connection freezes,
or is very (very) slow. I get up to 90% of lost packets when pinging a machine
in my LAN, and times up to 8000ms.
If I disable the power management, everything is fine.
According to the wireless-iwl-power.conf configuration file, my chip is
supported,
but I see I do not have any /sys/class/net/*/device/power_level file (the
interface
is wlan0).
I just see /sys/class/net/wlan0/device/power/wakeup with kernel 2.6.32 and an
extra control
file in the same directory with kernel 2.6.35
I have the issue with both kernels (from unstable and experimental).
lspci shows:

Region 0: Memory at d2500000 (64-bit, non-prefetchable) [size=8K]
Capabilities: <access denied>
Kernel driver in use: iwlagn
I haven't seen anything in the logs related to this problem, and I do not know
how to try and
debug this.
I would be happy to test anything which might help you or upstream debug this.
Cheers,
Julien
