Since upgrading my old Acer laptop from jessie to stretch this week, I
have several unresolved issues.  Any help would be appreciated.

1)  Sometimes unresponsive.  In up-to-date jessie, I could have two
instances of firefox-esr open with multiple tabs and get reasonable
response.  In stretch, sometimes performance is completely normal, but
at random intervals, the desktop becomes unresponsive as disk activity
takes over.  Top shows firefox very active and ps shows a number of
kworker processes recently started.  But closing one browser and
reducing open tabs does not seem to matter.  How can I identify the
offending processes?  No hints appear in log files using the Linux 3.16
kernel.

2) Returning from xscreensaver screen blanking sometimes shows the
lightdm log in screen.  Ctrl-alt-F7 once or twice can get my session
back after an annoying pause.  This never happened on jessie.

3) With the new Linux 4.9.0-3-amd64 kernel standard with stretch, the
problems above were worse; response was periodically lagging, and every
return from screensaver caused this in the syslog:

> Jun 19 14:17:08 spike2 kernel: [ 2268.384149] [drm:drm_atomic_helper_commit_clea
> nup_done [drm_kms_helper]] *ERROR* [CRTC:26:pipe A] flip_done timed out

[Call Trace snipped]

ralph@spike2 ~$ zgrep "Call Trace" /var/log/syslog* |wc
    222    1899   17536

Going back to Linux 3.16.0-4-amd64 avoids all that.  Should I file a
bug?  Against which package?

3) The sound volume up/down function keys [Fn up/down arrow] no longer
respond (xfce4).  However the screen brightness keys function normally
[Fn left/right arrow].  The mute sound function key is also ignored [Fn
F8].  I can control volume with the mouse using pavucontrol or
gkrellm-volume.

I find nothing in the docs to enable these keys.  On the net, I found a
suggestion that only caused the keyboard setting app to run 100% cpu.

Again, any suggestions are welcome.  Thanks!
