SubjectBugs in 2.6.0-test1 and 2.6.0-test1-mm2
Date
Hi,

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
list).

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

,----
| CONFIG_INPUT_MOUSE=y
| CONFIG_MOUSE_PS2=y
| CONFIG_MOUSE_SERIAL=m
`----

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
frames).

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. :-(
