Suspend/Resume problems with Thinkpad 240

!Having said that, I run 5.2.1-RELEASE on my IBM Thinkpad A30p. Suspend/Resume
!works for me, but I had to remove GLX from my XF86Config file, otherwise the
!machine would hang on resume if I was running X11.

!The USB issue you describe is known. I don't know the specifics, but apparently
!someone is working on it, or has the issue on their ToDo list. It happens to
!me too.

I have 5.2.1-R running on my Toshiba Satellite Pro 6100.
APM suspend/resume have been working well on this hardware,
even with the Nvidia X11 driver.
While looking at the USB resume problem (had it here, too),
I found that compiling a kernel with "option USB_DEBUG",
then enabling kernel debug messages on uhci with
"sysctl hw.usb.uhci.debug=1" brings USB back every time.

OK, there's a little overhead due to the extra debugging code,
and a few extra kernel messages around suspend/resumes,
but the notebook hasn't needed a reboot in a couple weeks due to a
failed suspend/resume
(actually, only one reboot since building this kernel due to an unrelated
[I think!] problem).
