Hi Ben,

Sorry, was trying to squeeze in a quick reply in between classes=2E =20

Yes, I did a dist-upgrade, and a new kernel was installed, and DKMS did ru=
n=2E  I will try purging and reinstalling the client tonight, that should a=
ddress any mismatches, yes?  I'll also remove any other kernels and headers=
 at the same time, just to be sure=2E

Thanks,
Richard
