The system is frozen bef= ore the latency task is created. Sometimes Adeos is at odds with mainline changes in the MTRR code when it gets preempted by some real-time activity, so it is important to check the behavior with no X11 started, plain console mode. If things end up working in this mode, then this might give us some hints about the issue. >=20 >=20 > Mit freundlichen Gr=C3=BC=C3=9Fen / Best Regards > Bernd Benner > MH/SGT3 > moehwald > Bosch Group > Moehwald GmbH > Michelinstra=C3=9Fe 21 > 66424 Homburg > GERMANY > www.moehwald.de > b.benner@domain.hid > Moehwald GmbH, Sitz/Registered Office: Homburg/Saar, Zentrales Handelsreg= ister/Registered Court: Saarbr=C3=BCcken HRB 2812 > Gesch=C3=A4ftsf=C3=BChrung/Managing Directors: Jens Last, Wolfgang Geenen >=20 >=20 > -----Urspr=C3=BCngliche Nachricht----- > Von: Gilles Chanteperdrix [mailto:gilles.chanteperdrix@xenomai.org] > Gesendet: Freitag, 13.

We had a problem r= evealed by grub2, I do not remember which version fixed it. Otherwise, you = have to enable early printk and redirect the console to serial port or netc= onsole, in order to capture it from another computer.
