I'm coding a Module using UML. That module calls tcp_alloc_pskb() inside the kernel. That function allocates memory for a socket buffer inside the network sending path used inside the kernel. But iam calling it inside my module. But calling it in my module gives me a: Kernel panic: Kernel mode fault at addr 0x28, ip 0xa003d050 And then the whole UML goes down. No chance to make a backtrace, because gdb is killed too. While playing with breakpoints i got that message, but only one time: 0xa0109d14 in sig_handler (sig=-1610608640, sc= {gs = 1024, __gsh = 0, fs = 64304, __fsh = 40959, es = 53718, __esh = 16406, ds = 28232, __dsh = 16417, edi = 1075922592, esi = 1075922592, ebp = 1073912488, esp = 1, ebx = 0, edx = 1073911876, ecx = 8, eax = 2, trapno = 2684353328, err = 1075922600, eip = 1412, cs = 18080, __csh = 16417, eflags = 0, esp_at_signal = 2684353276, ss = 9185, __ssh = 16405, fpstate = 0x9ffffb30, oldmask = 12, cr2 = 1075908832}) at trap_user.c:105 105 } (gdb) That gave me the hint, that it could possibly a uml specific problem. Can anybody please help me to solve my problem ? Is there any chance to make a backtrace even if gdb was completly killed ? What does that error message mean ? Where can i start searching for the error ? Or any other ideas ?
