Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-11
Severity: normal

I was having problems with WPA-encrypted networks in heavy load
conditions, e.g. when transferring files from a local server.
Every minute I would be disconnected with the error messages

TKIP: ICV error detected: STA=...
N/A: Michael MIC verification failed for MSDU from ... keyidx=0
wifi0: MSDU decryption/MIC verification failed (SA=... keyidx=0)
TKIP: received packet without ExtIV flag from ...

And after about 1 minute, the wireless reconnected again.

After googling a while, I found this page:
http://www.tuxyturvy.com/blog/index.php?/archives/23-Using-the-IPW3945-with-Linux,-WPA,-and-the-SMP-Kernel.html

That is exactly my setup, and my error. I don't know which ieee80211
version is included with the 2.6.18 kernel, but I'm experiencing this
problem, and there is one more comment mentioning 2.6.18

Apparently, this is the same bug in Ubuntu:
https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/56894

I had a quick look at the 2.6.20 changelog, and it contains

commit 4d1feabcbf41f875447a392015acd0796f57baf6
Author: Ulrich Kunitz <kune@deine-taler.de>

    [PATCH] zd1211rw: Call ieee80211_rx in tasklet
    
    The driver called ieee80211_rx in hardware interrupt context.  This has
    been against the intention of the ieee80211_rx function.  It caused a bug
    in the crypto routines used by WPA.  This patch calls ieee80211_rx in a
    tasklet.

That could be the relevant changeset, I don't know. There are some more 80211
related patches that could be relevant.
Anyway, not having reliable networking is a bigger issue for me...
