(I don't have APIC on my laptop) root@logo:~# zcat /proc/config.gz | grep APIC CONFIG_X86_GOOD_APIC=3Dy # CONFIG_X86_UP_APIC is not set Only the second one can be changed in make (menu)config.

IIRC, this didn't work, system hangs at resume as well. Will try again if=20 you've released an updated version. =2D-=20 Christian --nextPart2797575.SD178IPKMa Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.9.15 (GNU/Linux) iD8DBQBC5MLwlZfG2c8gdSURAmn+AJ487ffSM9Sp59MrVjg7j5+WgLcKBgCgqLJL sI/R1bAZj228Sm1URraVR44= =kEcx -----END PGP SIGNATURE----- --nextPart2797575.SD178IPKMa--
