The poison message has not reappeared but this morning there was a
sudden break in the connection. Only toggling the wifi via rfkill
brought things back to life. dmesg below:

Another weird thing that I've noticed with 2.6.30 kernels (although it
might be happening with older ones) is that periodically (maybe once a
day) the packet loss between the computer and the access point will
become very high and will stay that way until the computer is rebooted.
I do not know if toggling via rfkill will also solve that problem.
