So it's almost getting to be a habit: yet another -rc release that is delayed by a couple of days.
However, this time I actually have an excuse. Well, an excuse other than my usual "Sue me, I'm disorganized and forgot".
This time the reason for the delay is that we spent several days chasing down a nasty floating point state corruption that happens on 32-bit x86 - but only if you have a modern CPU (why are you using 32-bit kernels?) that supports the AES-NI instructions. And then you have to enable support for them *and* use a wireless driver that uses it. The most likely reason for that is using the mac80211 infrastructure with WPA with AES encryption (ie usually WPA2).
Anyway, if you are using wireless networking, have a modern CPU that you cripple by running in 32-bit mode, and have seen odd FP-related rashes with (the usual symptoms seem to be flash problems in the browser or the mouse in X suddenly moving to a corner or similar, but anything goes, really), that might be due to this.
