Subject: iwl3945 in 2.6.24-rc1 dies under load
Date: Wed, 31 Oct 2007 01:52:40 +0100 [thread overview]
Message-ID: <20071031005202.GA1534@elf.ucw.cz> (raw)
Hi!
...does not seem to work too well :-(. It connects with the AP
(good!), and survives some "normal" use, but it died at first big
tcpspray (baaaad!).

...unfortunately, microcode sources are not available so Intel should
fix this, right?
(Actually, it recovered after 3 minutes):

Hmm, and it is pretty reproducible, with:
