Trying your hint with adding=20 "options i2c_i801 disable_features=3D0x20" to /etc/modprobe.d/i2c_i801.conf doesn't seem to solve it for me. root@laptop64:/root # systool -v -m i2c_i801 Module =3D "i2c_i801" Attributes: coresize =3D "28672" initsize =3D "0" initstate =3D "live" refcnt =3D "0" srcversion =3D "A40BF457CFB8C7887EB2045" taint =3D "" uevent =3D Parameters: disable_features =3D "32" Sections: .bss =3D "0xffffffffc0801800" .data =3D "0xffffffffc0801120" .exit.text =3D "0xffffffffc07fe463" .gnu.linkonce.this_module=3D "0xffffffffc08014c0" .init.text =3D "0xffffffffc070b000" .note.gnu.build-id =3D "0xffffffffc07ff000" .orc_unwind =3D "0xffffffffc0800140" .orc_unwind_ip =3D "0xffffffffc07ffe38" .parainstructions =3D "0xffffffffc07ff548" .rodata.str1.1 =3D "0xffffffffc07ff284" .rodata.str1.8 =3D "0xffffffffc07ff028" .rodata =3D "0xffffffffc07ff560" .smp_locks =3D "0xffffffffc07ff280" .strtab =3D "0xffffffffc070d350" .symtab =3D "0xffffffffc070c000" .text =3D "0xffffffffc07fc000" __jump_table =3D "0xffffffffc0801000" __mcount_loc =3D "0xffffffffc08005d0" __param =3D "0xffffffffc07ffe10" __verbose =3D "0xffffffffc0801220" My system boots legacy grub in text mode (KMS) and seems to keep hanging even with that option set.
