Most recent kernel where this bug did *NOT* occur: Unknown. Have only had SD
working using Vanilla Kernel.
Hardware Environment: IBM/Lenovo Thinkpad z61m (9540-HAG)
Software Environment: Gentoo with Vanilla Kernel.
Problem Description: Laptop will suspend & resume normally, unless the tifm_7xxx
and related modules have been loaded for SD card access. Once loaded, even if
the modules are unloaded before suspend, the kernel will hangup after showing

on the console. Sometimes it prints various messages about the USB bus
(Dependent on whether USB modules loaded, devices on bus etc), and it prints a
message about the SD card slot as well. Then nothing. A power cycle is them
Steps to reproduce:
Boot linux. Load tifm_7xxx modules (Inlcuding tifm_core tifm_7xx1 mmc_core
mmc_block tifm_sd). Then attempt to suspend. Unloading all the modules before
suspend also results in same effect.
This should be corrected by the last patch set submitted to -mm.

Tested in 126.96.36.199 and confirmed that I can now suspend & resume with the TIFM drivers loaded...
