Created an attachment (id=389147) --> (http://bugzilla.novell.com/attachment.cgi?id=389147) [details] dmesg after Xorg hangs and task list requested

Thanks. Nice example of AA deadlock: [<ffffffff814a00ea>] mutex_lock+0x1a/0x40 [<ffffffffa02bc94b>] wacom_resume+0x3b/0x90 [wacom] [<ffffffff81327a32>] usb_resume_interface+0xd2/0x190 [<ffffffff81327b5d>] usb_resume_both+0x6d/0x110 [<ffffffff81327c24>] usb_runtime_resume+0x24/0x40 [<ffffffff8130a2cf>] __pm_runtime_resume+0x26f/0x450 [<ffffffff8130a23a>] __pm_runtime_resume+0x1da/0x450 [<ffffffff8130a53a>] pm_runtime_resume+0x2a/0x50 [<ffffffff81328176>] usb_autopm_get_interface+0x26/0x60 [<ffffffffa02bc626>] wacom_open+0x36/0x90 [wacom] wacom_open took wacom->lock and calls usb_autopm_get_interface which in turn calls wacom_resume which tries to aquire the lock again.

Yes, it should help generally. Actually I wonder, why usbcore.autosuspend=0 didn't help you... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
