A "normal" severity for a bug that causes the system to be
completely unusable when the package is in use? That locks up the system
like Fort Knox? That causes data loss if any files are still open? I'm
hard pressed to think of a more severe problem.
There are no proprietary gpu drivers, and please re-read the post.
One of the systems is Intel. Both systems were upgraded from Debian "Lenny"
with no problems whatsoever running KDE3. Neither has any problem running
gnome. KDE4 was so unusable on the Pentium system I wiped the drive and
installed fresh from the "Squeeze" installer. It didn't help. Both use the
graphics processors embedded on the motherboard, with plain-vanilla Debian
installations straight from the Debian install CD. The Pentium system is an
old Dell Optiplex GX-1 system, which is about as Plain Jane Intel as it
gets. The AMD is over a year old. All of the software on both machines -
other than that I have written myself - is straight from the Debian
repositories.
I'll try upgrading the kernel on the AMD system. The Pentium is not
local to me, and an upgrade failure would probably be unrecoverable.
