Well, the problem with this bug is how hard it is for me to reproduce.
I'm willing to admit that just because I never got it before 2.6.32
isn't proof that it wasn't there in 2.6.31. But it's a regression
somewhere along the line, since I've been using this hardware for over 3
years now. There were lots of bugs in the sky2 driver years ago, but
for the last 2+ years or so, I haven't had any trouble at all until now.
The bug only shows up for me with bittorrent traffic. I also use the
same adapter to transfer backups over the network from several
computers, and that doesn't trigger it...
I used 2.6.31 for however long it was the current stable, and I never
got a crash with it. After I got several crashes in 2.6.32, I reverted
to 2.6.31 until Jarek sent this patch that seems to have fixed it. I've
never gotten it to crash in 2.6.31, so I'm pretty sure it's a 2.6.32
regression, but I can't prove it.
I would love to do more testing, but since I can't reproduce the bug at
will, I'm not really sure what to offer?
