Hello,
i have applied the 2.2.14aa1 Patch, but things went uglier.
Now i am unable to get my KDE Desktop fully started. X is starting, then
KDE with lots of windows starting and then comes the hard lock. With
2.2.14 i sometimes get locks when starting my X-Desktop but not always.
May be it is something in the scheduling code which gets confused when
lots of running programs are in the queue (i haven't had a deeper look
at the code now).
Are there any hints ?
Is it possible to debug a running and then frozen kernel ?
Have fun,
Juergen
