Subject: [2.6.29-git12 iwl3945] wlan0: beacon loss from AP 00:19:5b:e7:a2:f8 - sending probe request

Wireless card:
08:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG
[Golan] Network Connection (rev 02)

I have compiled 2.6.29-git12. Comparing to 2.6.29 (stable) I have
message in dmesg:

wlan0: beacon loss from AP 00:19:5b:e7:a2:f8 - sending probe request

Also iwconfig shows slow Bit Rate (1 Mb/s). Connection seems be
stable, but it never happen in 2.6.29.

Hmm, you probably need to distinguish what your real problem is, and
what you think
the problem is. I have a few
"wlan2: beacon loss from AP <mac_address> - sending probe request" in
my dmesg since I upgraded
lately, but my wireless connectivity is fine. I think that message is
just the occasional informative/debug messages
that the kernel dev people add, just to be informative (and I am using
a different driver/hardware altogether).
