Dear All, I have an HP c8000 with two CPUs (PA-8800, 1GHz four cores) perfectly working with HP-UX v11: all the hardware is correcly detected and configured. I have installed Debian 8.0 "unstable" on a 160G PATA/IDE and on 72G SCSI disks. Installation looks good, BUT at boot time I have a kernel panic message (please see below for the details). The behaviour is deterministic. I'm bootin only with one HD and empty DVD drive. If you think useful I can post the complete list of boot messages (I'm working using serial console terminal using Serial_A port). For the sake of completness, the very same kernel panic arrives using keyboard and monitor attached to the video card. The c8000 was perfectly OK with both UP-UX and Linux before the CPU (from 1 to two PA-8800) upgrade. Thanks in adavance for your help. In the meanwhile I'm going to step-back to Debian 5. I will keep up updated.
