           Summary: IBM X40 laptop does no longer resume
           Product: Drivers

     KernelVersion: 2.6.29-rc1
          Platform: All
        OS/Version: Linux

            Status: NEW
          Severity: normal
          Priority: P1

Latest working kernel version:2.6.28
Distribution: Debian unstable x86 32bit
Hardware Environment: Thinkpad X40 1.5GB mem, 1.2GHz Pentium M
Software Environment: Using the debian hibernate scripts.

When trying to resume from suspend-to-ram (via opening the lid), the system
hangs after turning on the cpu fan and the display backlight. The
suspend-indicator-led still shines. System is totally unresponsive, not even
SysRq can reboot it. But vga console seems to work, at least I can see the
blinking cursor. The only way to get out is to hold the power button for a few
secs.

git bisect points to:

commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703
Author: Alan Stern <stern at rowland.harvard.edu>

    USB: fix up suspend and resume for PCI host controllers

I'll now test whether reverting this commit helps. btw, there's nothing
connected to the usb bus besides the integrated bluetooth. Turning this off
(ie. disconnecting via firmwire-controlled keys) doesn't change anything in the
results.
