Hello, Kumar! Thank you again for your help...
The inscription of the CPU says: PPC8540 PX833LB 2L71V MSIA QEAD0412 (Yes, there is a heatsink on it ;-) root at PM854:/cdrom/crux/base$ cat /proc/cpuinfo processor : 0 cpu : e500 revision : 2.0 (pvr 8020 0020) bogomips : 823.29 Vendor : Freescale Semiconductor Machine : mpc8540ads clock : 825MHz PVR : 0x80200020 SVR : 0x80300020 PLL setting : 0x5 Memory : 256 MB I hope that this is current... Where can I find more information about the SVR? (I had a look to the Errata Sheets... but there is no overview of the different silicons.) Up to now, the Panic didn't appear again - I didn't change anything yet... I just try to setup a new system (CRUX) on the attached hdd. Best greets, Clemens Koller _______________________________ R&D Imaging Devices Anagramm GmbH Rupert-Mayer-Str. 45/1 81379 Muenchen Germany http://www.anagramm.de Phone: +49-89-741518-50 Fax: +49-89-741518-19 Kumar Gala wrote: > Clemens, > > I dont think there is really and debug to do with this.
