Please ignore this about nonvs. nonvs has nothing to do with the suspend/resume problem on this laptop. Instead it seems to involve reboots, which is crazy. From a cold power-on start, suspend resume will always fail. But if the laptop is rebooted first, suspend and resume appear to work. What the heck? I have no clue how to debug this. So now it appears that everything I ever tried to fix this only seemed to work because I rebooted after changing GRUB or module options. --=20 Knowledge Is Power Power Corrupts Study Hard Be Evil --=-YVcidAY6MNliwgXS/ON5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAk6GIeoACgkQ1IRuMHS+h7EsFACfaR44Pkr6pYVb3//DbpiDBE4Q 7i4AoM2FrBBkikzZ6eVVBRfpl5A9qUMS =Smp0 -----END PGP SIGNATURE----- --=-YVcidAY6MNliwgXS/ON5--
