Do you have reported the problem to the intel iwlwifi bugzilla ?
No, I haven't done that yet. Will do this asap.

I've been experiencing similar probs for months on a Dell E6500 w/ Intel 5300 agn. Unfortunately, in order to diagnose the issue, Intel wants the iwlagn module loaded with debugging options that produce a lot of output (a couple hundred MB per day or so when I tried it). More importantly, my experience has been that the problem never occurs when debugging options are turned on 8-(
