Hello, Sorry for the delay in the response. In fact, I believe it is not really a kernel panic, because the login message appears at the screen just before the screen is cleared (and the computer is blocked). Sometimes I can see the mouse pointer for X, but the computer is also blocked.
The boot behavior is something like this: - normal boot, which the messages on the screen (I suppose the messages are correct) - login message (terminal mode) - switch to X mode - system block Build information: - Linux kernel 2.6.30 - Xenomai version 2.4.9.1 (I have tried also with xenomai 2.4.9 and I had similar results) - GCC version 4.3.2 - Ubuntu 8.10 Which information can I send to you in order to be more specific? Thanks for your help.
