-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
I just upgrade my Tecra M2 this weekend to the latest GIT tree and noticed that my mouse pointer/touchpad is now broken on resume. Investigating, it appears that mouse device gets confused due to the introduced psmouse_reset(psmouse) during reconnect: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f3a5c73d5ecb40909db662c4d2ace497b25c5940 Before resume, this is the output I get: Jul 3 01:25:11 lapdance kernel: alps.c: E6 report: 00 00 64 Jul 3 01:25:11 lapdance kernel: alps.c: E7 report: 22 02 14 Jul 3 01:25:11 lapdance kernel: alps.c: E6 report: 00 00 64 Jul 3 01:25:11 lapdance kernel: alps.c: E7 report: 22 02 14 Jul 3 01:25:12 lapdance kernel: alps.c: Status: 05 01 0a Jul 3 01:25:12 lapdance kernel: alps.c: Enabling hardware tapping Jul 3 01:25:12 lapdance kernel: alps.c: Status: 05 01 0a Jul 3 01:25:12 lapdance kernel: input: DualPoint Stick on isa0060/serio1 Jul 3 01:25:12 lapdance kernel: input: AlpsPS/2 ALPS DualPoint TouchPad on isa0060/serio1 If I then suspend and resume: Jul 3 01:26:13 lapdance kernel: alps.c: E6 report: 00 00 64 Jul 3 01:26:13 lapdance kernel: alps.c: E7 report: 73 02 0a Jul 3 01:26:14 lapdance kernel: alps.c: E6 report: 00 00 64 Jul 3 01:26:14 lapdance kernel: alps.c: E7 report: 73 02 0a Jul 3 01:26:14 lapdance kernel: alps.c: Status: 15 01 0a Jul 3 01:26:14 lapdance kernel: alps.c: Enabling hardware tapping Jul 3 01:26:14 lapdance kernel: alps.c: Status: 15 01 0a Jul 3 01:26:14 lapdance kernel: input: PS/2 Mouse on isa0060/serio1 Jul 3 01:26:14 lapdance kernel: input: AlpsPS/2 ALPS GlidePoint on isa0060/serio1 The pointer is confused, and a hard shutdown and boot is required to restore it. A reboot alone won't do the trick. FWIW, I was using the regular IMPS/2 X mouse driver, though I later tried using the synaptics X driver and that didn't work either. Other things I've tried include trying psmouse_reset until it returns successfully, though sometimes it did, and other times it didn't, even after 100 retries. In either case the pointer didn't come back. Removing the psmouse_reset makes the pointer come back properly 100% of the time. Are you sure that the psmouse_reset is really the right thing to do? (worked fine in 2.6.11-rc2).
