The ehci-hcd driver fails in exactly the same place. 2. It was still v. unstable, which led me to investigate why (since I'm pretty sure the hardware is good & the suse compiler is supposed to be a good one). I started stripping out options until eventually I found that it's devfs that's the culprit - with that enabled I get random compile errors every few seconds. With it disabled the compile works perfectly, even with the debian compiler (tried -j20 and -j255 and both passed). My first guess was you can't use a 32bit devfsd with a 64bit kernel, but stopping devfsd didn't seem to make a whole lot of difference to the stability... only compiling out the entire devfs system solved it. I suppose it could be insmod breaking the ehci-hcd... I'll see if I can find a pure 64bit one (presumably suse have one) rather than the biarch one that debian uses. Tony
