Hi Maciej,

I can confirm that the two FDDI cards work on a 32-bit kernel. I'm not 
getting anywhere near the data rates I'd expect (3.5MB/sec?) but it's a 
start.  I'd be glad to help test any 64-bit patches you come up with, 
Maciej.

Either way, Eric Dumazet's patch to drivers/block/aoe/aoecmd.c seems to 
be required to prevent a panic right after defxx is loaded.  Eric - good 
find.  Should your patch be submitted upstream, then?

Dave O.
