    -----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 01:25:12 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: 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).

    Thanks,

    Mike Waychison
