Now that you say it...
I'm having problems with wireless networking (wpi(4)) on my laptop,
using WPA2. wpa_supplicant(9) frequently complains about disconnections/
reconnections, and TCP connections stall sometimes. I was suspecting
aging hardware, but now I've checked "vmstat -m" and found a
significant number of "calls to protocol drain routines".
The kernel is from mid-december, but the problem has started
to manifest at least some weeks before.
With a wired (bge(4)) connection I don't see anything suspicious.

best regards
Matthias
