[Bug 559163] Re: Dell Latitude D600 hangs on wakeup from suspend

[sennight]

Thank you soren121 - the HAL replacement was what I was thinking of but
couldn't remember.  Talking about hardware got me curious, so I pulled
out a Dell docking station (D/APR PR01X) and suspended the laptop. So
far suspend/resume almost always fails when the laptop is on its own,
but when the laptop is docked, suspend/resume works perfectly!

Did some more digging.  When the D600 is docked, not only is there a
difference in the listed modules in /var/log/pm-suspend.log (to be
expected?), but there is also a change in the order in which they are
listed (see attached).  Specifically:

Module                  Size  Used by
nls_iso8859_1           3249  0 
nls_cp437               4919  0 
vfat                    8901  0 
fat                    47767  1 vfat

As far as I can tell, these four modules appear only when the D600 is
UNDOCKED and does NOT suspend/resume successfully.  There may be other
differences as well.  Might try blacklisting them and see what happens.

Again, apologies if something is unclear or I'm not providing enough
specific info.
