Summary: Thinkpad T410s fails to suspend with 2.6.34 kernel
unless hid_ntrig is blacklisted
Product: ACPI

Regression: No
I have a Thinkpad T410s with multitouch monitor, running Ubuntu 10.04. With
kernel 2.6.34, suspend fails with messages
usbhid 2-1.8:1.1: suspend error -5
pm_op(): usb_dev_suspend+0x0/0x20 returns -5
PM: Device 2-1.8 failed to suspend async: error -5
PM: Some devices failed to suspend
That's the ntrig controller, judging by these startup messages.

When I blacklist the hid_ntrig module, then suspend works.
