Hi,

after an upgrade some weeks ago (after the new Debian was released), my
system irregularly slows down for some (about 10, sometimes up to 30)
seconds.

These moments, the system reacts very slowly and the mouse moves very
sluggish. A CPU meter like htop shows no significant usage at these
moments. I don't find anything suspicious in the kernel or xserver logs.
There is no significant hard disk usage.

The same problem happens when using 3.8, but not when using 3.2 (so I
guess it has something to do with the kernel).

I use a Thinkpad R500 with an Intel i915 graphics card and an Intel Core
2 Duo.

I don't know if it has something to do with this problem, but also
/sys/devices/platform/dock.0/docked gives a wrong value with this new
kernel versions.

This bug makes the system almost unusable. The only workaround is using
the old kernel version.


Thanks,
Christian

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
