kernel upgrade disaster, hotplug and linux-image-2.6.15-1-686
I tried upgrading kernels today (from 2.6.11 to 2.6.15).
My motivation was my computer being intermittently and non-reproducibly unresponsive for long times (>30 sec) when viewing large images (example: http://upload.wikimedia.org/wikipedia/en/0/05/Coronary_artery_bypass_surgery_Image_657B-PH.jpg ) when using Firefox and/or Mozilla. Now, I know that large images are going to work the computer-- and I can't expect an instant response... but my gut says what is happening isn't right and there is problem somewhere.
When Firefox deals with these large images I cannot drop to a console and kill Firefox-- the keyboard is essentially unresponsive and the mouse has a huge time delay in responsiveness. I don't think this is right-- and my suspicion was and still is a kernel/memory management problem of some sort (as unlike http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=360079 -- I have keyboard locking outside of Firefox & Mozilla).
Any case, Firefox aside (and perhaps some unrealistic expectations), the upgrade was disaster.
After the upgrade
-the display was bad-- it looked like the refresh rate was too high
-sound was pooched
-wireless interface was pooch
What happened is below in detail.
My question-- before trying another kernel upgrade or considering taking a stab at 2.6.14:
1. Is the package 'libc6-i686' essential for replacing the functionality of the 'hotplug' package?
2. Does not purging 'hotplug' cause problems? (During the install of 2.6.15 it said that ought to be done.)
3. Is anyone aware of issues with 2.6.11 -- and the locking behaviour I get with Firefox & Mozilla?
Thanks,
Michael

----will try to reboot back to windows
undo earlier changes
----reboot back to debian
mouse busted
diagnosis: since hotplug was removed X11 chokes 'cause it can't find the mouse
----then download 'hotplug' deb with windows to /mnt/transfer (the fat32 drive I share between Win XP & debian)
rebooted to debian
apt-get remove linux-image-2.6.15-1-686 udev
dpkg --install hotplug...
reboot (as after the remove of 'linux-image-2.6.15-1-686 udev' it said I ought to)
after reboot -- X11 loaded again :) (back to where I started)
