[gentoo-hardened] linux-2.6.16-hardened-r11 issues (*.14-*-r8 is o.k.)

[dnlt0hn5ntzhbqkv51]

linux-2.6.14-hardened-r8 runs great; loads fast and seems to function properly.
 
linux-2.6.16-hardened-r11 loads a little slower (especially during startup udev), and runs great for a day or two 'til suddenly the mouse cursor becomes "trapped" within 1/2 inch of the left border of my screen.
 
- I've tried radeon and fglrx drivers in X; no difference.
 
- r8 and r11 are configured comparably.
 
- I've googled about for this, and found no help..........
 
 
Any ideas, please?
 
TIA

A few of us were experiencing this same problem.. 
Many countless hours of frustration and many recompiles of things 
in vein.. In the end I noticed that somehow preempt became enabled in my
kernel. I don't recall enabling it or anything... 
Anyway disable PREEMPT in your kernel and the problem should go away.

What we noticed is it only seems to happen to laptop/synaptics users..

I have the following enabled in my 2.6.16-hardened-r11 kernel:

CONFIG_PREEMPT=y
CONFIG_PREEMPT_BKL=y

Should the the above be set to OFF? Thanks!

For what its worth (and currently that system is offline due to me
attempting (and failing miserably) at installing Gentoo/FreeBSD, but I
had Preempt on although I believe I had preempt the big kernel lock off,
and used pci=noacpi in my kernel line and didn't seem to run into any
more issues with the cursor.  Of course, turning off preempt worked as
well :)

I've enabled PREEMPT, but kept BIG LOCK preemption off.
Two hardened machines (Athlon MP - radeon, Celeron M - i830/i915) have
been running fine, although I do not use synaptics on the laptop because
lack of touchpad.

Regards,
Dw.

I have just started to install web/email servers using Gentoo hardened 2.6.x kernel for the first time last week. My first 2.6.x Gentoo server is still being tested! I always have questioned/concerned the new Linux kernel naming convention that each 2.6.x version of the kernel would not have the time needed to mature (like the 2.4.x kernel) and that each and every one of them would have incurred different bugs and compatibility issues. This thread is just one of the many examples.
