I really started to go nuts on this contradicting patterns. Your box seems to be worse than the VAIO, it has some random surprise generator built in :) > > Is the 32 bit kernel working on that box ? > > Can't tell, I have only 64-bit userland here. Should be fine. The check is there since late 2.6.21-rc. I really could kick my own ass that I did not remember the nx6325 wreckage in the 2.6.21-rc time frame. Sigh, way too much broken hardware out there to keep track of it. > > Thanks for your patience. > > Well, I'm only making sure that future kernels will run on my box. ;-) Nothing wrong with that. Thanks again for your help, tglx
