Default Bug#498328: linux-image-2.6.26-1-amd64: nice is not "fair": mouse jumps and chars repeated in terminal

Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-4
Severity: normal

Hello,
I updated 2 days ago to this kernel, and I start notice pretty soon this
problem: when I execute a program of mine (even with nice -n 19), with 4
parallel thread (it's cpu bound), the system completely slow down, the mouse
starts jumping (not a smooth movement), switching to other application is
really slow and the programs starts repeating input chars randomly (verified
with amsn and gnome-terminal): this is what I came out trying a "ls /proc...":

$ llllllllllllllllllllllllllllllllllllllllllllllllll lls /procccccccccccccccccccccccc/2808

The funny thing is that this machine has boinc always running (on 4 cores) and
I cannot experience any of the above problem.

I used the default configuration shipped along with this kernel.

Please let me know anything I can do to help you fix is.

Thanks,
Sandro

Today the situation was much more worst (after 3 days of uptime):
while trying to access to mysql from terminal, I start typing 'm' char
and then the drama begins: the 'm' char was repeating forever (and
it's not a faulty keyboard, since I remove the battery and the flow
kept going) in every window I choose, both terminals, xchat,
iceweasel, etc. in the current virtual desktop and in others

After a while, the whole machine start "ranting": switching to other
virtual desktop result in freezed windows, trying to exit from the DE
(xfce in this case) was not possible since xfce-panel was not
responding, and not even ssh from another pc worked!!

Please treat this as a grave bug (I didn't raise the severity to that
level because I still don't know if it's RC or not). I renew my offer
to support you in any way to debug & fix it. I saw a -5 was released:
I'll try it but from changelog it doesn't seem to address this
problem.

Thanks in advance,
Sandro

Hi Havis, I'm forwarding your reply to the bug log, so the maintainer
can have a better idea of the situation.

Given your workaround (I'm not going to replicate) it's even more
clearer a bug in the kernel needing to be fixed before Lenny release.

Sandro
