Here are some links: http://thread.gmane.org/gmane.linux.kernel/1222803 https://bugzilla.kernel.org/show_bug.cgi?id=3D37632 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D658778 http://ubuntuforums.org/showthread.php?t=3D1444822 This still happens on my K53E on v3.4-rc2-16-ga9e1e53. Unbinding just one of two controllers doesn't help. Disabling /sys/bus/pci/devices/0000:00:1[ad].0/power/wakeup doesn't help. echo mem>/sys/power/state doesn't hang with 'core' in /sys/power/pm_test, only with 'none'. Windows 7 enters S3 perfectly well. I didn't see any other suggestions how to debug this. I can provide any debug data if that will help. This seems to be a very important problem for owners of certain devices. --=20 WBR, wRAR --+HP7ph2BbKc20aGI Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBCAAGBQJPhbd+AAoJEDNi9wMaSZLhp54P/RjclP/bzQa98+Qf9gRRPMYh A3pj900dR+EjdNe2oSOv7iGhnIYiShGmi+z3dE/dihtcSDXVzn9/HKdTpfuetbbL 6f6EbgzbLbzG33aB1F6KXNgVkgi3UFyO9JOtsRWpN5/01gWm60qwgnusQnTO7A6U Zwo0MI5INctb0t5GhcP17BMEspRDdU/T7kNkRK+1wxN5c68FvjDr52cYq9v+8Vtk C1DSJiUxLn0K/htwx+AgDAQMZMvfMO8R8JVgx27Io05WeYPPYappauBKvsEMGirQ ffG/0eArFWkWHHV2l43rUV+U1nOa+as2Qt3OrWSpi85rb5K/juqQalYo7aprtK2k qjddJc2HtbngdTP4c1+xo3EQOj7k5UvYdNSlG8RwrZpTcVbzpfLLBgRHzPgWKjBp SJT39Wqp2k/bdx0mZUGgDTXi4js00UFYBZo1GJnuMRSv0xk6iuSOEEwljwZ+Aw8C bkY/bo3x6S2WchTSr+zaVV4NqpjrnFj1foCZIyJw3QFVZY5UFYbdQDdHcR3efAib /CiHt82GCiietu77Jw5c359Ek/jeikyQP5iIkY9q8t1Zy/JxRyl36UTu9yr4uiwo 8WYUgYsjmWUMEqvNTDG76Kr95/X1tKsVT5KJJqLqTTUqo4cXN6z+2mZr6XuhfJ7Z IuugfF0ZqVO4E+OP2EzX =VrjQ -----END PGP SIGNATURE----- --+HP7ph2BbKc20aGI-- -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
