Re: suspend problems between 4.2R and 4.5 ?

Well, FWIW, I've noticed that suspect is failing for me now and I know it 
used to work.  As it happens, on my 512M laptop, a suspend to disk takes 
longer than shutdown/reboot sequence, though, so I very rarely use this 
feature, so I'm not sure quite when or why it broke.

My is set up only to suspend to memory and it used to be ok; now it actualy 
suspends ok but it crashes quite regularly upon resume.

Dell Inspiron 8000.  I frankly doubt that this is connected to your case, 
though--as it as it may sounds I know that mine was working the last time I 
did a kernel update (which was when I applied the 2nd ATA hot-swap fixes, and 
I specifically tested suspend.

It seems to be somehow connected to some user-level program I've started 
running since then, but I haven't figure out what yet.  It is very tiresome 
testing this since after it crashes it has to re-fsck my 67G worth of HD 
space . . .
