Bugs in 2.6.0-test1 and 2.6.0-test1-mm2

I did a quick test of the mentioned kernels (BTW, the -mm2 version was
very responsive on my desktop!) and found two very annoying bugs (apart
from the "cannot mount root fs" bug already mentioned on this mailing

1. My PS/2 Logitech Mouseman Wheel mouse doesn't work preperly any
   more. When I run xev and press different mouse buttons, I get the
   following events:
   left button - button 1
   right button - button 3
   both middle button and thumb button - button 2 (should be different)
   wheel - no events at all. :-(

   I did not change everything in the XFree86 configuration and it works
   properly widh 2.4.* kernels (i.e. there are 6 different events). The
   kernel is compiled with

2. The second bug is a very strange one. I use sawfish as a WM and have
   some shortcuts to launch frequently used apps. For example, when I
   press Ctrl-Alt-Space, gnome-terminal is launched.

   Now, when CPU load is high, those shortcuts do not work reliably. The
   first time I press Ctrl-Alt-Space nothing happens. However it I press
   those keys again, 3 (three!) terminals show up! An so on, so I always
   get this sequens: 0 - 3 - 0 - 3 - 0 - 3... That is, if I press
   Ctrl-Alt-Space 3 times, I get 9 terminals! And no, it's not a joke! ;-)
   It looks so: the first terminal appears without a frame, then it
   freezes for about 2 seconds, then the frame is drawn around the
   terminal, and then 2 other terminals show up almost immediately (with

   This bug can only be reproduced during high CPU load with both
   official and -mm2 kernels. I have a dual Athlon box, but it's enough
   to utilize one CPU to encounter this behavior. Note, that it only
   happens whan I use these shortcuts; if I launch gnome-terminal with
   the mouse from the gnome panel or type gnome-terminal in a shell,
   such things do not happen.

   I don't know, maybe this is just another sawfish bug, but it always
   worked with 2.4 kernels. Are there other similar WM-independent app
   launchers so I can compare?

P.S. While I was writing this text (and compiling the kernel with make
-j2), my system froze for abount 10-15 minutes, so I could not do
anything. :-(
